aws direct connect logical redundancy

No, you can assign/configure separate AWS side ASN for each AWS Direct Connect gateway, not each VIF. For publicly addressable AWS resources (for example, Amazon S3 buckets, Classic EC2 instances, or EC2 traffic that goes through an internet gateway), if the outbound traffic is destined for public prefixes owned by the same AWS payer account and actively advertised to AWS through an AWS Direct Connect public virtual Interface, the Data Transfer Out (DTO) usage is metered toward the resource owner at the AWS Direct Connect data transfer rate. Yes. Please note we cant promise that ports will be available on the same chassis if you want to add more ports in the future. Javascript is disabled or is unavailable in your browser. Q: Can I use any ASN - public and private? Yes, a transit virtual interface will support jumbo frames. For MACsec to work, your dedicated connection must be transparent to Layer 2 traffic and the device terminating the Layer 2 adjacency must support MACsec. The port-hour charges for the two separate 200 Mbps Hosted Connections will be summarized under a single item with a label ending in HCPortUsage:200M. Q: Which type of AWS Direct Connect connections support MACsec? At this time, we only allow v4 BGP session running single VPN tunnel with IPv4 address. AWS Direct Connect Partners can help you extend your preexisting data center or office network to a AWS Direct Connect location. Q: Can virtual private gateways (VGWs, associated with a VPC) be part of more than one AWS Direct Connect gateway? Q: Can I use different private ASNs for my AWS Direct Connect Gateway and Virtual Private Gateway? This location offers logical redundancy over a single virtual interface (VIF) on a Direct Connect connection. This can reduce the number of Border Gateway Protocol sessions between your on-premises network and AWS deployments. AWS Direct Connect SiteLink requires BGP. No, we do not support moving the VLAN tag outside of the encrypted payload. MACsec is not supported on 1 Gbps dedicated connections or any hosted connections. Q: Does AWS Direct Connect SiteLink support local preference BGP communities? You can use the AWS Management Console or AWS Direct Connect application programming interface (API). You can configure your VIF to enable or disable AWS Direct Connect SiteLink using the AWS Management Console, AWS Command Line Interface, or APIs. If the 10 Gbps fails or the prefix is withdrawn, the 1 Gbps interface becomes the return path. Learn more about AWS Direct Connect pricing. Q: What is an AWS Direct Connect gateway? You can also consider multi-region failover with Transit Gateway Cross Region Peering and Direct Connect Gateway. Q: Can I see my past test history when using the failover test feature? You can cancel AWS Direct Connect by deleting your ports from the AWS Management Console. You can configure/assign an ASN to be advertised as the AWS side ASN during creation of the new AWS Direct Connect gateway. Q: Can I delete a single port from my LAG? Once deployed, you can connect your equipment to AWS Direct Connect using a cross-connect. The AWS side ASN you receive depends on your private virtual interface association. Yes, you can resize the VPC. A private virtual interface enables access to your VPC. Features that are not currently supported by AWS Direct Connect are; AWS Classic VPN, AWS VPN (such as edge-to-edge routing), VPC peering, VPC endpoints. You can advertise the default route via BGP. Infrastructure. AWS Direct Connect SiteLink supports IPv6. Q: What are the technical requirements for virtual interfaces to public AWS services, such as Amazon EC2 and Amazon S3? You can find more details about advertised IP prefixes and Direct Connect Routing policy here. Q: Can I create a LAG out of my existing ports? You can use the AWS Management Console or API operations to create transit virtual interface. When the test is cancelled, we restore the Border Gateway Protocol session, and your test history reflects that the test was canceled. For details on creating, updating, associating/disassociating, and deleting a LAG refer to the AWS Direct Connect documentation: Link aggregation groups - AWS Direct Connect. For example, consider the bill for a customer with two separate 200 Mbps Hosted Connections at an AWS Direct Connect location, and no other Hosted Connections at that location. Yes. High-speed connections, such as 100 Gbps dedicated connections, can quickly exhaust MACsecs original 32-bit packet numbering space, which would require you to rotate your encryption keys every few minutes to establish a new Connectivity Association. Q: What is an AWS Direct Connect Gateway Bring your own private ASN? No, an AWS Direct Connect gateway will not route traffic between a VPN and an AWS Direct Connect VIF. For customers with a Japanese billing address, use of AWS services is subject to Japanese Consumption Tax. Q: Can I send traffic from a VPC that is associated with an AWS Direct Connect gateway to another VPC associated to the same AWS Direct Connect gateway? Q: When using the failover test feature, can I configure the duration of the test or cancel the test while it's running? We suggest you create the new VIFs on your new LAG, and then move the connections over to the new LAG once youve created all of your VIFs. Maximum transmission unit (MTU) size will be limited to 8,500. An AWS Direct Connect gateway is a globally available resource. We recommend establishing a second connection for redundancy. We want to protect customers from BGP spoofing. Q: Can I use AWS Direct Connect to reach resources running in AWS Local Zones? Q: Are there additional fees when using AWS Direct Connect gateway and working with remote AWS Regions? Cloud WAN, currently in preview, can create and manage networks of VPCs across multiple Regions. Q: How can I get started with AWS Direct Connect? You select a resiliency model, and then the AWS Direct Connect Resiliency Toolkit guides you through the dedicated connection ordering process. When planning your connectivity, work with your selected Partner(s) to determine which of the above best practices are right for your needs, and learn how your selected Partner(s) can enable you to achieve them. If you do not specify Local Preference communities for your private VIF, the default local preference is based on the distance to the AWS Direct Connect Locations from the local Region. To use the Amazon Web Services Documentation, Javascript must be enabled. AWS recommends customers use multiple dynamically routed, rather than statically routed, connections to AWS at multiple AWS Direct Connect locations. (Details can be found in the Virtual private gateway associations entry in our documentation.). You can also connect to the AWS Local Zones using AWS Direct Connect Public Virtual Interfaces using an Internet Gateway (IGW). When connecting to any AWS region, your data will not hairpin via the home region if it is not in the shortest path to your desired AWS region. It is important to note that single VPN tunnel bandwidth is still limited to 1.25 Gbps. Yes. Q: What is the format for Hosted Connection port-hour charges? Q: Why is an AWS Direct Connect gateway necessary? Dynamic LACP bundles are used; static LACP bundles are not supported. terminate on separate devices in one location. AWS Direct Connect data transfer usage will be aggregated to your management account. You will pay applicable egress data charges based on the source remote AWS Region and port hour charges. In the case of the private virtual interface, the AWS account that owns the AWS resources responsible for the Data Transfer Out will be charged. Q: How do I create a segmented network architecture with AWS Direct Connect SiteLink? Yes, you can configure the AWS side of the BGP session with a private ASN and your side with a public ASN. Q: Does AWS Direct Connect SiteLink require an AWS Direct Connect gateway connection? If the virtual interface is connected to a VPC, and you choose to have AWS automatically generate the peer IP CIDR, the IP address space for both ends of the connection is allocated by AWS and is in the 169.254.0.0/16 range. You can continue to attach your virtual interfaces (VIFs) to virtual private gateways (VGWs). Traffic will ingress to the parent Region first before connecting back to your AWS Local Zones. Yes, provided the current AWS Direct Connect Gateway is not associated with an AWS Transit Gateway. No. The following communities are supported for private virtual interface and are evaluated in order of lowest to highest preference. Q: Who can initiate a failover test using the AWS Direct Connect Resiliency Toolkit? For more information, see Using the AWS Direct Connect Resiliency Toolkit to get started. Q: How will I be charged and billed for my use of AWS Direct Connect? You can create one transit virtual interface on the 4x10G LAG. It will not be available for hosted connections. Ranges for 16-bit private ASNs include 64512 to 65534. As shown in the figure above, such a topology provides resilience to device failure, connectivity failure, and complete location failure. You can create the AWS Direct Connect gateway in any Region and access it from all other Regions. No, you cannot attach private virtual interface to your AWS Transit Gateway. No, AWS Direct Connect gateway's only support routing traffic from AWS Direct Connect VIFs to VGW (associated with VPC). It works with any type of AWS Direct Connect connection (dedicated or hosted). Click here to return to Amazon Web Services homepage, AWS Direct Connect Resiliency Recommendations. No. Q: How do I request a cross connect at an AWS Direct Connect location? Q: Do you support all the Border Gateway Protocol (BGP) attributes that you support on the private virtual interface for the transit virtual interface? You can view the AWS side ASN in the AWS Direct Connect console and in the response of the DescribeDirectConnectGateways or DescribeVirtualInterfaces API operations. Yes, AWS Direct Connect offers an SLA. Details are here. No, you need to make connections between the local service providers used at your on-premises locations, or work with an AWS Direct Connect Delivery Partner, to connect to AWS Direct Connect locations. Thanks for letting us know we're doing a good job! After you have downloaded your Letter of Authorization and Connecting Facility Assignment (LOA-CFA), you must complete your cross-network connection. Yes, you can use this feature to influence egress traffic behavior between two VIFs on the same physical connection. Sign in to your AWS Management Console to order AWS Direct Connect today! Themaximum transmission unit of the LAG can be changed. We treat all links as equal, so we wont set link priority on any specific link. This can be accomplished by advertising prefixes over the primary/active virtual interface with a community for higher local preference than prefixes advertised over the backup/passive virtual interface. Q: Does AWS Direct Connect offer a Service Level Agreement (SLA)? No. Then, associate your Virtual Gateway (VGW) to an AWS Direct Connect private virtual interface, or AWS Direct Connect Gateway, to make the connection. Traffic to/from public resources will be routed over the internet. You will still have intra-Region VPC connectivity, and will be charged the egress rate for the related geographic Regions. You must advertise public IP prefixes (/31or smaller) that you ownor are AWS-providedvia BGP. AWS Direct Connect is now live at Equinix NY5, Secaucus, NJ. Q: Youre out of ports and I have to order a new LAG, but I have Virtual Interfaces (VIFs) configured. Prefixes marked with the same communities, and bearing identical MED*, AS_PATH attributes are candidates for multi-pathing. For Hosted Connections, connection speeds of 50 Mbps, 100 Mbps, 200 Mbps, 300 Mbps, 400 Mbps, 500 Mbps, 1 Gbps, 2 Gbps, 5 Gbps and 10 Gbps may be ordered from approved AWS Direct Connect Partners. Q: I have created an AWS Direct Connect gateway with one AWS Direct Connect VIF, and three non-overlapping VGW-VPC pairs, what happens if I detach one of the virtual private gateways (VGW) from the AWS Direct Connect gateway? If you dont selectminimum links, it will default to zero. Q: Which AWS Regions offer AWS Direct Connect support for AWS Transit Gateway? You can use AssociateVirtualInterface API or console to do this operation. You can create up to 51 virtual interfaces per 1 Gbps, 10 Gbps, or 100 Gbps dedicated connection inclusive of the transit virtual interface. Yes, you can review your test history using the AWS Management Console or through AWS CloudTrail. No, you can create only one transit virtual interface for any AWS Direct Connect connection of capacity greater than or equal to 1 Gbps. How long do you keep the test history? Please note this will cause your ports to go down for a moment while they are reconfigured as a LAG. This feature is backward compatible with pre-existing methods for achieving failover; if your connection is currently configured for failover, no additional changes are necessary. To get started with planning your connectivity to AWS, visit our Getting Started page. Q: Will this feature be available on both Public and Private Virtual Interfaces? Q: What is the AWS Direct Connect Resiliency Toolkit? AWS Local Zones do not support AWS Transit Gateway at this time. Your data travels directly to and from AWS Local Zones over an AWS Direct Connect connection, without traversing an AWS Region. There is no extra charge for using a LAG. See the AWS Direct Connect User Guidefor more detailed requirements information. AWS VPN CloudHub enables connectivity between on-premises networks using AWS Direct Connect or a VPN within the same Region. Asynchronous BFD is automatically enabled for each AWS Direct Connect virtual interface, but will not take effect until it's configured on your router. For more details, consult the. Yes, as long as the VPC route table has routes to the virtual private gateway (VGW) towards the VPN. If I associate this VGW to an AWS Direct Connect gateway, can I send traffic from my VPN to a VIF attached to the AWS Direct Connect gateway in a different AWS Region? Q: What are the quotas associated with transit virtual interface? Supported browsers are Chrome, Firefox, Edge, and Safari. Q: If I associate virtual private gateways (VGWs) to an AWS Direct Connect gateway, can I continue to use all VPC features? Q: I'm attaching multiple private VIFs to a single AWS Direct Connect gateway. You can select your own private ASN in the AWS Direct Connect gateway console. Q: I want to select a 32-bit ASN. Q: Which MACsec cipher suites do you support? Yes, you can have a single port in a LAG. The resiliency models are designed to ensure that you have Bring up multiple AWS Direct Connect gateways, and associate subsets of AWS Direct Connect SiteLink-enabled private virtual interfaces (VIFs) with each. LAG will only include ports on the same AWS Direct Connect devices. When using AWS Direct Connect, you can connect to VPCs deployed in any AWS Region and Availability Zone. Q: How can I tell what Im being charged for AWS Direct Connect SiteLink? Q: Can I use same private ASNs for my AWS Direct Connect Gateway and Virtual Private Gateway? A single 40 GE interface connecting to a 4x 10 GE LACP is not supported. Q: Can I use the same private network connection with Amazon Virtual Private Cloud (VPC) and other AWS services simultaneously? With AWS Direct Connect, you will pay AWS Direct Connect data transfer rates for origin transfer. Q: What is the difference between dedicated and hosted connections? High Resiliency: You can achieve high resiliency for Please refer to AWS Direct Connect User Guideto review supported and not supported traffic patterns. Yes, there are differences. In other words, AWS ports send Link Aggregation Control Protocol Data Units (LACPDUs) continuously. Q: Do I need a new AWS Direct Connect connection to use MACsec with my MACsec-capable device? Virtual interfaces may be configured to access AWS services such as Amazon EC2 and Amazon S3 using public IP space, or resources in a VPC using private IP space. No, this feature is currently available for private and transit virtual interfaces only. Q: Can I have v4 and v6 BGP sessions running over a single VPN tunnel? Q: If I use an AWS Direct Connect gateway, does my traffic to the desired AWS Region go by way of the associated home AWS Region? NOTE: The limitations on MTU size and single flow do not apply to AWS Direct Connect connectivity to the AWS Local Zone in Los Angeles. 802.1AE MAC Security (MACsec) is an IEEE standard that provides data confidentiality, data integrity, and data origin authenticity. You can use AWS Direct Connect gateway to access any AWS Region (except AWS Regions in China) from any AWS Direct Connect locations. Q: If I have only two ports in my LAG can I still delete one? Q: Can I add more transit virtual interfaces to the connection? AWS Direct Connect does not provide managed QoS functionality. To do this, you must create a new private virtual interface, and at the time of creation, associate it with your AWS Direct Connect gateway. Bear in mind that local preference is evaluated before the AS_PATH attribute. You can use existing AWS Direct Connect local preference tags with AWS Direct Connect SiteLink. No, data transfer between Availability Zones in a Region will be billed at the regular Regional data transfer rate in the same month in which the usage occurred. AWS Direct Connect SiteLink, on the other hand, connects DX locations together, bypassing AWS Regions to improve performance. To build a simple network, configure a private virtual interface (VIF) and enable AWS Direct Connect SiteLink on that VIF at each site. AWS Direct Connect has two separate charges: port hours and data transfer. Q: What are the technical requirements for virtual interfaces (VIF) to VPCs? Q: If I have established IPv4 and IPv6 Border Gateway Protocol sessions, can I run this test for each Border Gateway Protocol session? Q: If I have a virtual private gateway (VGW) attached to a VPN and an AWS Direct Connect gateway, and my AWS Direct Connect circuit goes down, will my VPC traffic route out to the VPN? Q: What is multi-account support for AWS Direct Connect gateway? Q: Can I allocate transit virtual interface in another AWS account? Q: Where can I select my own private ASN? When using AWS Direct Connect gateway, your traffic will take the shortest path to and from your AWS Direct Connect location to the destination AWS Region, regardless of the associated home AWS Region of the AWS Direct Connect location where you are connected. Q: How do I add links to my LAG once its set up? The VIF type can be private or transit. Please refer to this documentto learn more about this feature. Yes. AWS Direct Connect is one of multiple connectivity options that you will be able to use with a Cloud WAN network in the future. Q: How wide will AWS multipath traffic to my network? An AWS Direct Connect gateway performs several functions: Q: Can I associate more than one AWS Transit Gateway with an AWS Direct Connect gateway? In addition to the AWS global infrastructure, AWS Direct Connect offers several features to help support your data resiliency and backup needs. Q: What is a virtual private gateway (VGW)? AWS Direct Connect gateway does not support AWS VPN CloudHub functionality. Virtual private gateway(s) and AWS Transit Gateway(s) can be in different AWS accounts than the account that owns the AWS Direct Connect gateway. Dynamic routing also enables remote connections to automatically leverage available preferred routes, if applicable, to the on-premises network. Using AWS Direct Connect, you can establish private connectivity between AWS and your datacenter, office, or colocation environment, which in many cases can reduce your network costs, increase bandwidth throughput, and provide a more consistent network experience than Internet-based connections. It is important to understand that AWS Site to Site VPN supports up to 1.25 Gbps throughput per VPN tunnel and does not support Equal Cost Multi Path (ECMP) for egress data path in the case of multiple AWS Site to Site VPN tunnels terminating on the same VGW. I would like to receive all traffic for this destination across the 10 Gbps AWS Direct Connect connection, but still be able to failover to the 1 Gbps connection. Q: Does AWS Direct Connect SiteLink support IPv6? Partial port hours consumed are billed as full hours. Provision sufficient network capacity to ensure that the failure of one network connection does not overwhelm and degrade redundant connections. At this time, we only support IPv4 endpoint address for VPN. LAGs streamline configuration because the LAG configuration applies to all connections in the group. Q: How does AWS Direct Connect differ from an IPsec VPN Connection? See the AWS GovCloud (US) User Guide for detailed instructions on setting up AWS Direct Connect for use with the AWS GovCloud (US) Region. Pricing is per port-hour consumed for each port type. They will not come back up until LAG is configured on your side. This page documents our best practices for ensuring high resiliency with AWS Direct Connect. Traffic from your on-premises network to the detached VPC will stop, and VGW's association with the AWS Direct Connect gateway will be deleted. No, an AWS Transit Gateway can only be associated with the AWS Direct Connect gateway attached to transit virtual interface. Ifminimum links are set to three, you can then delete a port from the LAG. For additional resiliency, AWS customers can consider using AWS Site to Site VPN terminating on an AWS Transit Gateway as a back up to their AWS Direct Connect connections. Q: Can I use my current AWS Direct Connect Gateway (DXGW) to associate the Virtual Gateway (VGW)? Yes, you can create one transit virtual interface on any connection of capacity of 1 Gbps or more (1, 2, 5, 10, 100 Gbps). MACsec is supported on 10 Gbps and 100 Gbps dedicated AWS Direct Connect connections at selected points of presence. Yes. If, for example, you have four ports, yourminimum links is set to three, and you only have two active ports, your bundle will not be active. operate applications and databases that automatically fail over between Availability Zones without interruption. No, you cannot attach transit virtual interface to your Virtual Private Gateway. No, a LAG doesn't make your connectivity to AWS more resilient. Maximum Resiliency: You can achieve maximum resiliency Q: What ports types will this be available on? Note that these capacity identifiers will appear by location depending on which Hosted Connection capacities you have at each location. AWS has set the BFD liveness detection minimum interval to 300, and the BFD liveness detection multiplier to 3. This will prevent all network traffic flowing over that virtual interface until you reduce the number of routes to less than 100. You can associate multiple virtual private gateways (VGWs, associated with a VPC) to an AWS Direct Connect gateway, as long as the IP CIDR blocks of the Amazon VPC associated with the Virtual Private Gateway do not overlap. To create a hub-and-spoke architecture, create an AWS Direct Connect gateway and associate it with all AWS Direct Connect SiteLink-enabled private VIFs. You can also provide 32-bit ASNs between 4200000000 and 4294967294. Q: Do I need any special hardware to use MACsec? If you are using a public ASN, you must own it. Q: Can you create a tool to move my virtual interfaces (VIFs) for me? Using the AWS Direct Connect Resiliency Toolkit to get started. No, we will continue to respect AS_PATH attribute. For more information about AWS Regions and Availability Zones, see AWS Global To avoid this situation, the IEEE Std 802.1AEbw-2013 amendment introduced extended packet numbering, increasing the numbering space to 64-bits, easing the timeliness requirement for key rotation. No, Layer 2 connections are not supported. Amazon CloudFront supports custom origins including origins you run outside of AWS. They are in active/active. Once a transit VIF is connected to an AWS Direct Connect Gateway, that Gateway cannot also host another Private VIF - it is dedicated to the transit VIF. Maximum resilience is achieved by separate connections terminating on separate devices in more than one location. For prefixes that are advertised from your on-premises networks, each VPC associated with an AWS Direct Connect gateway receives all prefixes announced from your on-premises networks. For example, if you have 3x 1 G links, and would like to add a fourth, and we do not have a port available on that device, you must order a new LAG of 4x 1 G ports. RFC 3021 (Using 31-Bit Prefixes on IPv4 Point-to-Point Links) is supported on all Direct Connect virtual interface types. A new unused VLAN tag that you select. Only the owner of the AWS account that includes the virtual interface can initiate the test. available, fault tolerant, and scalable than traditional single or multiple data center infrastructures. Q: I have already configured my routers with AS_PATH, do I need to change the configuration to use community tags and disrupt my network? No, you cannot associate an unattached VGW to AWS Direct Connect gateway. Q: What does a simple two-site network architecture look like with AWS Direct Connect SiteLink? AWS Direct Connect Partners help customers establish network connectivity between AWS Direct Connect locations and their data centers, offices or colocation environments. Minimumlinks is a feature in LACP where you can set the minimum number of links that must be active in a bundle for that bundle to be active and pass traffic. Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. Q: Is there a way to configure an AWS Direct Connect gateway to selectively propagate prefixes to/from VPCs? Yes. It will be available for 1 G, 10 G, and 100 G Dedicated Connection ports. If your existing MACsec connection is not terminated on a MACsec-capable device, you can request a new MACsec-capable connection using the AWS Management Console or the CreateConnection API. In the case of a transit virtual interface, the AWS account that owns the Amazon Virtual Private Cloud(s) attached to the AWS Transit Gateway associated with the AWS Direct Connect gateway attached to the transit virtual interface is charged. Q: Do I need new AWS Direct Connect connections to use AWS Direct Connect SiteLink, and do they need to be the same type? Prefixes belonging to CloudFront locations that are not inside the Amazon backbone network will not be advertised through Direct Connect. If you are configuring a virtual interface to the public AWS Cloud, the IP addresses for both ends of the connection must be allocated from public IP space that you own. For non-critical production workloads and development workloads that do not require high resiliency, it is recommended to have at least two connections terminating on different devices at a single location. AWS Direct Connect gateway enables connectivity between on-premises networks and VPCs in any AWS Region. Q: Will Regional data transfer be billed at the AWS Direct Connect rate? Yes. Q: What is the default behavior, in case I do not use the supported communities? Q: How long does it take to establish an association between AWS Transit Gateway and AWS Direct Connect gateway? Q: I have an existing private virtual interface associated with virtual private gateway (VGW), can I associate my existing private virtual interface with an AWS Direct Connect gateway? Q: I currently have a VPN in us-east-1 attached to a virtual private gateway (VGW). If you resize your VPC, you must resend the proposal with the resized VPC CIDR to the AWS Direct Connect gateway owner. By attaching transit virtual interface(s) (VIF) to an AWS Direct Connect gateway and associating AWS Transit Gateway(s) with the Direct Connect gateway, you can share transit virtual interface(s) to connect with up to three AWS Transit Gateways. Q: Are there limits on the number of routes I can advertise towards AWS using AWS Direct Connect? Highly resilient connections requireredundant hardware, even when connecting from the same physical location. Your device configuration also must change appropriately. Q: I have 4x10 Gbps LAG, how many transit virtual interfaces can I create on this link aggregation group (LAG)? Q: When I associate my existing AWS Direct Connect connection with a LAG, what happens with virtual interfaces (VIFs) already created with a connection? The resiliency models are designed to ensure that you have the appropriate number of dedicated connections in multiple locations. If you do not have a backup AWS Direct Connect link or an IPsec VPN link, then Amazon VPC traffic will be dropped in the event of a failure. Q: Can I create transit virtual interface on 1/2/5/10/100 Gbps hosted connection? Existing AWS VPN CloudHub functionality will continue to be supported. Learn more. To improve failover times between paths when using multiple LAGs, bidirectional forwarding detection (BFD) is supported. Q: Do you require the use of Extended Packet Numbering (XPN)? If you want to limit traffic to and from any specific VPC, you should consider using Access Control Lists (ACLs) for each VPC. For information about how to use VPN with AWS Direct Connect, see AWS Direct Connect Plus VPN. The location preference communities for private and transit virtual interfaces provides you a feature to let you influence the return path for traffic sources from VPC(s). Depending on your use case, you might choose one, the other, or both. Yes. You work with a Direct Connect Partnerif you need assistance extending your office or data center network to a AWS Direct Connect location.

No, you can assign/configure separate AWS side ASN for each AWS Direct Connect gateway, not each VIF. For publicly addressable AWS resources (for example, Amazon S3 buckets, Classic EC2 instances, or EC2 traffic that goes through an internet gateway), if the outbound traffic is destined for public prefixes owned by the same AWS payer account and actively advertised to AWS through an AWS Direct Connect public virtual Interface, the Data Transfer Out (DTO) usage is metered toward the resource owner at the AWS Direct Connect data transfer rate. Yes. Please note we cant promise that ports will be available on the same chassis if you want to add more ports in the future. Javascript is disabled or is unavailable in your browser. Q: Can I use any ASN - public and private? Yes, a transit virtual interface will support jumbo frames. For MACsec to work, your dedicated connection must be transparent to Layer 2 traffic and the device terminating the Layer 2 adjacency must support MACsec. The port-hour charges for the two separate 200 Mbps Hosted Connections will be summarized under a single item with a label ending in HCPortUsage:200M. Q: Which type of AWS Direct Connect connections support MACsec? At this time, we only allow v4 BGP session running single VPN tunnel with IPv4 address. AWS Direct Connect Partners can help you extend your preexisting data center or office network to a AWS Direct Connect location. Q: Can virtual private gateways (VGWs, associated with a VPC) be part of more than one AWS Direct Connect gateway? Q: Can I use different private ASNs for my AWS Direct Connect Gateway and Virtual Private Gateway? This location offers logical redundancy over a single virtual interface (VIF) on a Direct Connect connection. This can reduce the number of Border Gateway Protocol sessions between your on-premises network and AWS deployments. AWS Direct Connect SiteLink requires BGP. No, we do not support moving the VLAN tag outside of the encrypted payload. MACsec is not supported on 1 Gbps dedicated connections or any hosted connections. Q: Does AWS Direct Connect SiteLink support local preference BGP communities? You can use the AWS Management Console or AWS Direct Connect application programming interface (API). You can configure your VIF to enable or disable AWS Direct Connect SiteLink using the AWS Management Console, AWS Command Line Interface, or APIs. If the 10 Gbps fails or the prefix is withdrawn, the 1 Gbps interface becomes the return path. Learn more about AWS Direct Connect pricing. Q: What is an AWS Direct Connect gateway? You can also consider multi-region failover with Transit Gateway Cross Region Peering and Direct Connect Gateway. Q: Can I see my past test history when using the failover test feature? You can cancel AWS Direct Connect by deleting your ports from the AWS Management Console. You can configure/assign an ASN to be advertised as the AWS side ASN during creation of the new AWS Direct Connect gateway. Q: Can I delete a single port from my LAG? Once deployed, you can connect your equipment to AWS Direct Connect using a cross-connect. The AWS side ASN you receive depends on your private virtual interface association. Yes, you can resize the VPC. A private virtual interface enables access to your VPC. Features that are not currently supported by AWS Direct Connect are; AWS Classic VPN, AWS VPN (such as edge-to-edge routing), VPC peering, VPC endpoints. You can advertise the default route via BGP. Infrastructure. AWS Direct Connect SiteLink supports IPv6. Q: What are the technical requirements for virtual interfaces to public AWS services, such as Amazon EC2 and Amazon S3? You can find more details about advertised IP prefixes and Direct Connect Routing policy here. Q: Can I create a LAG out of my existing ports? You can use the AWS Management Console or API operations to create transit virtual interface. When the test is cancelled, we restore the Border Gateway Protocol session, and your test history reflects that the test was canceled. For details on creating, updating, associating/disassociating, and deleting a LAG refer to the AWS Direct Connect documentation: Link aggregation groups - AWS Direct Connect. For example, consider the bill for a customer with two separate 200 Mbps Hosted Connections at an AWS Direct Connect location, and no other Hosted Connections at that location. Yes. High-speed connections, such as 100 Gbps dedicated connections, can quickly exhaust MACsecs original 32-bit packet numbering space, which would require you to rotate your encryption keys every few minutes to establish a new Connectivity Association. Q: What is an AWS Direct Connect Gateway Bring your own private ASN? No, an AWS Direct Connect gateway will not route traffic between a VPN and an AWS Direct Connect VIF. For customers with a Japanese billing address, use of AWS services is subject to Japanese Consumption Tax. Q: Can I send traffic from a VPC that is associated with an AWS Direct Connect gateway to another VPC associated to the same AWS Direct Connect gateway? Q: When using the failover test feature, can I configure the duration of the test or cancel the test while it's running? We suggest you create the new VIFs on your new LAG, and then move the connections over to the new LAG once youve created all of your VIFs. Maximum transmission unit (MTU) size will be limited to 8,500. An AWS Direct Connect gateway is a globally available resource. We recommend establishing a second connection for redundancy. We want to protect customers from BGP spoofing. Q: Can I use AWS Direct Connect to reach resources running in AWS Local Zones? Q: Are there additional fees when using AWS Direct Connect gateway and working with remote AWS Regions? Cloud WAN, currently in preview, can create and manage networks of VPCs across multiple Regions. Q: How can I get started with AWS Direct Connect? You select a resiliency model, and then the AWS Direct Connect Resiliency Toolkit guides you through the dedicated connection ordering process. When planning your connectivity, work with your selected Partner(s) to determine which of the above best practices are right for your needs, and learn how your selected Partner(s) can enable you to achieve them. If you do not specify Local Preference communities for your private VIF, the default local preference is based on the distance to the AWS Direct Connect Locations from the local Region. To use the Amazon Web Services Documentation, Javascript must be enabled. AWS recommends customers use multiple dynamically routed, rather than statically routed, connections to AWS at multiple AWS Direct Connect locations. (Details can be found in the Virtual private gateway associations entry in our documentation.). You can also connect to the AWS Local Zones using AWS Direct Connect Public Virtual Interfaces using an Internet Gateway (IGW). When connecting to any AWS region, your data will not hairpin via the home region if it is not in the shortest path to your desired AWS region. It is important to note that single VPN tunnel bandwidth is still limited to 1.25 Gbps. Yes. Q: What is the format for Hosted Connection port-hour charges? Q: Why is an AWS Direct Connect gateway necessary? Dynamic LACP bundles are used; static LACP bundles are not supported. terminate on separate devices in one location. AWS Direct Connect data transfer usage will be aggregated to your management account. You will pay applicable egress data charges based on the source remote AWS Region and port hour charges. In the case of the private virtual interface, the AWS account that owns the AWS resources responsible for the Data Transfer Out will be charged. Q: How do I create a segmented network architecture with AWS Direct Connect SiteLink? Yes, you can configure the AWS side of the BGP session with a private ASN and your side with a public ASN. Q: Does AWS Direct Connect SiteLink require an AWS Direct Connect gateway connection? If the virtual interface is connected to a VPC, and you choose to have AWS automatically generate the peer IP CIDR, the IP address space for both ends of the connection is allocated by AWS and is in the 169.254.0.0/16 range. You can continue to attach your virtual interfaces (VIFs) to virtual private gateways (VGWs). Traffic will ingress to the parent Region first before connecting back to your AWS Local Zones. Yes, provided the current AWS Direct Connect Gateway is not associated with an AWS Transit Gateway. No. The following communities are supported for private virtual interface and are evaluated in order of lowest to highest preference. Q: Who can initiate a failover test using the AWS Direct Connect Resiliency Toolkit? For more information, see Using the AWS Direct Connect Resiliency Toolkit to get started. Q: How will I be charged and billed for my use of AWS Direct Connect? You can create one transit virtual interface on the 4x10G LAG. It will not be available for hosted connections. Ranges for 16-bit private ASNs include 64512 to 65534. As shown in the figure above, such a topology provides resilience to device failure, connectivity failure, and complete location failure. You can create the AWS Direct Connect gateway in any Region and access it from all other Regions. No, you cannot attach private virtual interface to your AWS Transit Gateway. No, AWS Direct Connect gateway's only support routing traffic from AWS Direct Connect VIFs to VGW (associated with VPC). It works with any type of AWS Direct Connect connection (dedicated or hosted). Click here to return to Amazon Web Services homepage, AWS Direct Connect Resiliency Recommendations. No. Q: How do I request a cross connect at an AWS Direct Connect location? Q: Do you support all the Border Gateway Protocol (BGP) attributes that you support on the private virtual interface for the transit virtual interface? You can view the AWS side ASN in the AWS Direct Connect console and in the response of the DescribeDirectConnectGateways or DescribeVirtualInterfaces API operations. Yes, AWS Direct Connect offers an SLA. Details are here. No, you need to make connections between the local service providers used at your on-premises locations, or work with an AWS Direct Connect Delivery Partner, to connect to AWS Direct Connect locations. Thanks for letting us know we're doing a good job! After you have downloaded your Letter of Authorization and Connecting Facility Assignment (LOA-CFA), you must complete your cross-network connection. Yes, you can use this feature to influence egress traffic behavior between two VIFs on the same physical connection. Sign in to your AWS Management Console to order AWS Direct Connect today! Themaximum transmission unit of the LAG can be changed. We treat all links as equal, so we wont set link priority on any specific link. This can be accomplished by advertising prefixes over the primary/active virtual interface with a community for higher local preference than prefixes advertised over the backup/passive virtual interface. Q: Does AWS Direct Connect offer a Service Level Agreement (SLA)? No. Then, associate your Virtual Gateway (VGW) to an AWS Direct Connect private virtual interface, or AWS Direct Connect Gateway, to make the connection. Traffic to/from public resources will be routed over the internet. You will still have intra-Region VPC connectivity, and will be charged the egress rate for the related geographic Regions. You must advertise public IP prefixes (/31or smaller) that you ownor are AWS-providedvia BGP. AWS Direct Connect is now live at Equinix NY5, Secaucus, NJ. Q: Youre out of ports and I have to order a new LAG, but I have Virtual Interfaces (VIFs) configured. Prefixes marked with the same communities, and bearing identical MED*, AS_PATH attributes are candidates for multi-pathing. For Hosted Connections, connection speeds of 50 Mbps, 100 Mbps, 200 Mbps, 300 Mbps, 400 Mbps, 500 Mbps, 1 Gbps, 2 Gbps, 5 Gbps and 10 Gbps may be ordered from approved AWS Direct Connect Partners. Q: I have created an AWS Direct Connect gateway with one AWS Direct Connect VIF, and three non-overlapping VGW-VPC pairs, what happens if I detach one of the virtual private gateways (VGW) from the AWS Direct Connect gateway? If you dont selectminimum links, it will default to zero. Q: Which AWS Regions offer AWS Direct Connect support for AWS Transit Gateway? You can use AssociateVirtualInterface API or console to do this operation. You can create up to 51 virtual interfaces per 1 Gbps, 10 Gbps, or 100 Gbps dedicated connection inclusive of the transit virtual interface. Yes, you can review your test history using the AWS Management Console or through AWS CloudTrail. No, you can create only one transit virtual interface for any AWS Direct Connect connection of capacity greater than or equal to 1 Gbps. How long do you keep the test history? Please note this will cause your ports to go down for a moment while they are reconfigured as a LAG. This feature is backward compatible with pre-existing methods for achieving failover; if your connection is currently configured for failover, no additional changes are necessary. To get started with planning your connectivity to AWS, visit our Getting Started page. Q: Will this feature be available on both Public and Private Virtual Interfaces? Q: What is the AWS Direct Connect Resiliency Toolkit? AWS Local Zones do not support AWS Transit Gateway at this time. Your data travels directly to and from AWS Local Zones over an AWS Direct Connect connection, without traversing an AWS Region. There is no extra charge for using a LAG. See the AWS Direct Connect User Guidefor more detailed requirements information. AWS VPN CloudHub enables connectivity between on-premises networks using AWS Direct Connect or a VPN within the same Region. Asynchronous BFD is automatically enabled for each AWS Direct Connect virtual interface, but will not take effect until it's configured on your router. For more details, consult the. Yes, as long as the VPC route table has routes to the virtual private gateway (VGW) towards the VPN. If I associate this VGW to an AWS Direct Connect gateway, can I send traffic from my VPN to a VIF attached to the AWS Direct Connect gateway in a different AWS Region? Q: What are the quotas associated with transit virtual interface? Supported browsers are Chrome, Firefox, Edge, and Safari. Q: If I associate virtual private gateways (VGWs) to an AWS Direct Connect gateway, can I continue to use all VPC features? Q: I'm attaching multiple private VIFs to a single AWS Direct Connect gateway. You can select your own private ASN in the AWS Direct Connect gateway console. Q: I want to select a 32-bit ASN. Q: Which MACsec cipher suites do you support? Yes, you can have a single port in a LAG. The resiliency models are designed to ensure that you have Bring up multiple AWS Direct Connect gateways, and associate subsets of AWS Direct Connect SiteLink-enabled private virtual interfaces (VIFs) with each. LAG will only include ports on the same AWS Direct Connect devices. When using AWS Direct Connect, you can connect to VPCs deployed in any AWS Region and Availability Zone. Q: How can I tell what Im being charged for AWS Direct Connect SiteLink? Q: Can I use same private ASNs for my AWS Direct Connect Gateway and Virtual Private Gateway? A single 40 GE interface connecting to a 4x 10 GE LACP is not supported. Q: Can I use the same private network connection with Amazon Virtual Private Cloud (VPC) and other AWS services simultaneously? With AWS Direct Connect, you will pay AWS Direct Connect data transfer rates for origin transfer. Q: What is the difference between dedicated and hosted connections? High Resiliency: You can achieve high resiliency for Please refer to AWS Direct Connect User Guideto review supported and not supported traffic patterns. Yes, there are differences. In other words, AWS ports send Link Aggregation Control Protocol Data Units (LACPDUs) continuously. Q: Do I need a new AWS Direct Connect connection to use MACsec with my MACsec-capable device? Virtual interfaces may be configured to access AWS services such as Amazon EC2 and Amazon S3 using public IP space, or resources in a VPC using private IP space. No, this feature is currently available for private and transit virtual interfaces only. Q: Can I have v4 and v6 BGP sessions running over a single VPN tunnel? Q: If I use an AWS Direct Connect gateway, does my traffic to the desired AWS Region go by way of the associated home AWS Region? NOTE: The limitations on MTU size and single flow do not apply to AWS Direct Connect connectivity to the AWS Local Zone in Los Angeles. 802.1AE MAC Security (MACsec) is an IEEE standard that provides data confidentiality, data integrity, and data origin authenticity. You can use AWS Direct Connect gateway to access any AWS Region (except AWS Regions in China) from any AWS Direct Connect locations. Q: If I have only two ports in my LAG can I still delete one? Q: Can I add more transit virtual interfaces to the connection? AWS Direct Connect does not provide managed QoS functionality. To do this, you must create a new private virtual interface, and at the time of creation, associate it with your AWS Direct Connect gateway. Bear in mind that local preference is evaluated before the AS_PATH attribute. You can use existing AWS Direct Connect local preference tags with AWS Direct Connect SiteLink. No, data transfer between Availability Zones in a Region will be billed at the regular Regional data transfer rate in the same month in which the usage occurred. AWS Direct Connect SiteLink, on the other hand, connects DX locations together, bypassing AWS Regions to improve performance. To build a simple network, configure a private virtual interface (VIF) and enable AWS Direct Connect SiteLink on that VIF at each site. AWS Direct Connect has two separate charges: port hours and data transfer. Q: What are the technical requirements for virtual interfaces (VIF) to VPCs? Q: If I have established IPv4 and IPv6 Border Gateway Protocol sessions, can I run this test for each Border Gateway Protocol session? Q: If I have a virtual private gateway (VGW) attached to a VPN and an AWS Direct Connect gateway, and my AWS Direct Connect circuit goes down, will my VPC traffic route out to the VPN? Q: What is multi-account support for AWS Direct Connect gateway? Q: Can I allocate transit virtual interface in another AWS account? Q: Where can I select my own private ASN? When using AWS Direct Connect gateway, your traffic will take the shortest path to and from your AWS Direct Connect location to the destination AWS Region, regardless of the associated home AWS Region of the AWS Direct Connect location where you are connected. Q: How do I add links to my LAG once its set up? The VIF type can be private or transit. Please refer to this documentto learn more about this feature. Yes. AWS Direct Connect is one of multiple connectivity options that you will be able to use with a Cloud WAN network in the future. Q: How wide will AWS multipath traffic to my network? An AWS Direct Connect gateway performs several functions: Q: Can I associate more than one AWS Transit Gateway with an AWS Direct Connect gateway? In addition to the AWS global infrastructure, AWS Direct Connect offers several features to help support your data resiliency and backup needs. Q: What is a virtual private gateway (VGW)? AWS Direct Connect gateway does not support AWS VPN CloudHub functionality. Virtual private gateway(s) and AWS Transit Gateway(s) can be in different AWS accounts than the account that owns the AWS Direct Connect gateway. Dynamic routing also enables remote connections to automatically leverage available preferred routes, if applicable, to the on-premises network. Using AWS Direct Connect, you can establish private connectivity between AWS and your datacenter, office, or colocation environment, which in many cases can reduce your network costs, increase bandwidth throughput, and provide a more consistent network experience than Internet-based connections. It is important to understand that AWS Site to Site VPN supports up to 1.25 Gbps throughput per VPN tunnel and does not support Equal Cost Multi Path (ECMP) for egress data path in the case of multiple AWS Site to Site VPN tunnels terminating on the same VGW. I would like to receive all traffic for this destination across the 10 Gbps AWS Direct Connect connection, but still be able to failover to the 1 Gbps connection. Q: Does AWS Direct Connect SiteLink support IPv6? Partial port hours consumed are billed as full hours. Provision sufficient network capacity to ensure that the failure of one network connection does not overwhelm and degrade redundant connections. At this time, we only support IPv4 endpoint address for VPN. LAGs streamline configuration because the LAG configuration applies to all connections in the group. Q: How does AWS Direct Connect differ from an IPsec VPN Connection? See the AWS GovCloud (US) User Guide for detailed instructions on setting up AWS Direct Connect for use with the AWS GovCloud (US) Region. Pricing is per port-hour consumed for each port type. They will not come back up until LAG is configured on your side. This page documents our best practices for ensuring high resiliency with AWS Direct Connect. Traffic from your on-premises network to the detached VPC will stop, and VGW's association with the AWS Direct Connect gateway will be deleted. No, an AWS Transit Gateway can only be associated with the AWS Direct Connect gateway attached to transit virtual interface. Ifminimum links are set to three, you can then delete a port from the LAG. For additional resiliency, AWS customers can consider using AWS Site to Site VPN terminating on an AWS Transit Gateway as a back up to their AWS Direct Connect connections. Q: Can I use my current AWS Direct Connect Gateway (DXGW) to associate the Virtual Gateway (VGW)? Yes, you can create one transit virtual interface on any connection of capacity of 1 Gbps or more (1, 2, 5, 10, 100 Gbps). MACsec is supported on 10 Gbps and 100 Gbps dedicated AWS Direct Connect connections at selected points of presence. Yes. If, for example, you have four ports, yourminimum links is set to three, and you only have two active ports, your bundle will not be active. operate applications and databases that automatically fail over between Availability Zones without interruption. No, you cannot attach transit virtual interface to your Virtual Private Gateway. No, a LAG doesn't make your connectivity to AWS more resilient. Maximum Resiliency: You can achieve maximum resiliency Q: What ports types will this be available on? Note that these capacity identifiers will appear by location depending on which Hosted Connection capacities you have at each location. AWS has set the BFD liveness detection minimum interval to 300, and the BFD liveness detection multiplier to 3. This will prevent all network traffic flowing over that virtual interface until you reduce the number of routes to less than 100. You can associate multiple virtual private gateways (VGWs, associated with a VPC) to an AWS Direct Connect gateway, as long as the IP CIDR blocks of the Amazon VPC associated with the Virtual Private Gateway do not overlap. To create a hub-and-spoke architecture, create an AWS Direct Connect gateway and associate it with all AWS Direct Connect SiteLink-enabled private VIFs. You can also provide 32-bit ASNs between 4200000000 and 4294967294. Q: Do I need any special hardware to use MACsec? If you are using a public ASN, you must own it. Q: Can you create a tool to move my virtual interfaces (VIFs) for me? Using the AWS Direct Connect Resiliency Toolkit to get started. No, we will continue to respect AS_PATH attribute. For more information about AWS Regions and Availability Zones, see AWS Global To avoid this situation, the IEEE Std 802.1AEbw-2013 amendment introduced extended packet numbering, increasing the numbering space to 64-bits, easing the timeliness requirement for key rotation. No, Layer 2 connections are not supported. Amazon CloudFront supports custom origins including origins you run outside of AWS. They are in active/active. Once a transit VIF is connected to an AWS Direct Connect Gateway, that Gateway cannot also host another Private VIF - it is dedicated to the transit VIF. Maximum resilience is achieved by separate connections terminating on separate devices in more than one location. For prefixes that are advertised from your on-premises networks, each VPC associated with an AWS Direct Connect gateway receives all prefixes announced from your on-premises networks. For example, if you have 3x 1 G links, and would like to add a fourth, and we do not have a port available on that device, you must order a new LAG of 4x 1 G ports. RFC 3021 (Using 31-Bit Prefixes on IPv4 Point-to-Point Links) is supported on all Direct Connect virtual interface types. A new unused VLAN tag that you select. Only the owner of the AWS account that includes the virtual interface can initiate the test. available, fault tolerant, and scalable than traditional single or multiple data center infrastructures. Q: I have already configured my routers with AS_PATH, do I need to change the configuration to use community tags and disrupt my network? No, you cannot associate an unattached VGW to AWS Direct Connect gateway. Q: What does a simple two-site network architecture look like with AWS Direct Connect SiteLink? AWS Direct Connect Partners help customers establish network connectivity between AWS Direct Connect locations and their data centers, offices or colocation environments. Minimumlinks is a feature in LACP where you can set the minimum number of links that must be active in a bundle for that bundle to be active and pass traffic. Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. Q: Is there a way to configure an AWS Direct Connect gateway to selectively propagate prefixes to/from VPCs? Yes. It will be available for 1 G, 10 G, and 100 G Dedicated Connection ports. If your existing MACsec connection is not terminated on a MACsec-capable device, you can request a new MACsec-capable connection using the AWS Management Console or the CreateConnection API. In the case of a transit virtual interface, the AWS account that owns the Amazon Virtual Private Cloud(s) attached to the AWS Transit Gateway associated with the AWS Direct Connect gateway attached to the transit virtual interface is charged. Q: Do I need new AWS Direct Connect connections to use AWS Direct Connect SiteLink, and do they need to be the same type? Prefixes belonging to CloudFront locations that are not inside the Amazon backbone network will not be advertised through Direct Connect. If you are configuring a virtual interface to the public AWS Cloud, the IP addresses for both ends of the connection must be allocated from public IP space that you own. For non-critical production workloads and development workloads that do not require high resiliency, it is recommended to have at least two connections terminating on different devices at a single location. AWS Direct Connect gateway enables connectivity between on-premises networks and VPCs in any AWS Region. Q: Will Regional data transfer be billed at the AWS Direct Connect rate? Yes. Q: What is the default behavior, in case I do not use the supported communities? Q: How long does it take to establish an association between AWS Transit Gateway and AWS Direct Connect gateway? Q: I have an existing private virtual interface associated with virtual private gateway (VGW), can I associate my existing private virtual interface with an AWS Direct Connect gateway? Q: I currently have a VPN in us-east-1 attached to a virtual private gateway (VGW). If you resize your VPC, you must resend the proposal with the resized VPC CIDR to the AWS Direct Connect gateway owner. By attaching transit virtual interface(s) (VIF) to an AWS Direct Connect gateway and associating AWS Transit Gateway(s) with the Direct Connect gateway, you can share transit virtual interface(s) to connect with up to three AWS Transit Gateways. Q: Are there limits on the number of routes I can advertise towards AWS using AWS Direct Connect? Highly resilient connections requireredundant hardware, even when connecting from the same physical location. Your device configuration also must change appropriately. Q: I have 4x10 Gbps LAG, how many transit virtual interfaces can I create on this link aggregation group (LAG)? Q: When I associate my existing AWS Direct Connect connection with a LAG, what happens with virtual interfaces (VIFs) already created with a connection? The resiliency models are designed to ensure that you have the appropriate number of dedicated connections in multiple locations. If you do not have a backup AWS Direct Connect link or an IPsec VPN link, then Amazon VPC traffic will be dropped in the event of a failure. Q: Can I create transit virtual interface on 1/2/5/10/100 Gbps hosted connection? Existing AWS VPN CloudHub functionality will continue to be supported. Learn more. To improve failover times between paths when using multiple LAGs, bidirectional forwarding detection (BFD) is supported. Q: Do you require the use of Extended Packet Numbering (XPN)? If you want to limit traffic to and from any specific VPC, you should consider using Access Control Lists (ACLs) for each VPC. For information about how to use VPN with AWS Direct Connect, see AWS Direct Connect Plus VPN. The location preference communities for private and transit virtual interfaces provides you a feature to let you influence the return path for traffic sources from VPC(s). Depending on your use case, you might choose one, the other, or both. Yes. You work with a Direct Connect Partnerif you need assistance extending your office or data center network to a AWS Direct Connect location.
