Q: Why is an AWS Direct Connect gateway necessary? Show
An AWS Direct Connect gateway performs several functions:
Q: Can I associate more than one AWS Transit Gateway with an AWS Direct Connect gateway? You can associate up to three Transit Gateway to an AWS Direct Connect gateway as long as the IP CIDR blocks announced from your Transit Gateways do not overlap. Q: Can I associate VPCs owned by any AWS account with an AWS Direct Connect gateway owned by any AWS account? Yes, you can associate VPCs owned by any AWS account with an AWS Direct Connect gateway owned by any AWS account. Q: Can I associate AWS Transit Gateway that are owned by any AWS account with an AWS Direct Connect gateway that is owned by any AWS account? Yes, you can associate a Transit Gateway owned by any AWS account with an AWS Direct Connect gateway owned by any AWS account. 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? No. 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: Are there additional fees when using AWS Direct Connect gateway and working with remote AWS Regions? There are no charges for using an AWS Direct Connect gateway. You will pay applicable egress data charges based on the source remote AWS Region and port hour charges. See the AWS Direct Connect pricing page for details. Q: Do I need to use the same AWS account with my private/transit virtual interfaces(s), AWS Direct Connect gateway, Virtual Private Gateway, or AWS Transit Gateways in order to use an AWS Direct Connect gateway? Private virtual interfaces and AWS Direct Connect gateways must be in the same AWS account. Similarly, transit virtual interfaces and AWS Direct Connect gateways must be in the same AWS account. 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. Q: If I associate virtual private gateways (VGWs) to an AWS Direct Connect gateway, can I continue to use all VPC features? Networking features, such as Elastic File System, Elastic Load Balancing, Application Load Balancer, Security Groups, Access Control List, and AWS PrivateLink, work with AWS Direct Connect gateway. AWS Direct Connect gateway does not support AWS VPN CloudHub functionality. However, if you are using an AWS Site-to-Site VPN connection to a virtual gateway (VGW) that is associated with your AWS Direct Connect gateway, you can use your VPN connection for failover. 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. Q: I am working with an AWS Direct Connect Partner to get private virtual interface (VIF) provisioned for my account, can I use an AWS Direct Connect gateway? Yes, you can associate a provisioned private virtual interface (VIF) with your AWS Direct Connect gateway when you confirm that you are provisioned as private in your AWS account. Q: Can I connect to VPCs in my local Region? You can continue to attach your virtual interfaces (VIFs) to virtual private gateways (VGWs). You will still have intra-Region VPC connectivity, and will be charged the egress rate for the related geographic Regions. Q: What are the quotas associated with an AWS Direct Connect gateway? Please refer to the AWS Direct Connect quotas page for information on this topic. Q: Can virtual private gateways (VGWs, associated with a VPC) be part of more than one AWS Direct Connect gateway? No, a VGW-VPC pair cannot be part of more than one AWS Direct Connect gateway. Q: Can you attach a private virtual interface (VIF) to more than one AWS Direct Connect gateway? No, one private virtual interface can only attach to one AWS Direct Connect gateway OR one Virtual Private Gateway. We recommend that you follow AWS Direct Connect resiliency recommendations and attach more than one private virtual interface. Q: Does AWS Direct Connect gateway break existing AWS VPN CloudHub functionality? No, AWS Direct Connect gateway does not break AWS VPN CloudHub. AWS Direct Connect gateway enables connectivity between on-premises networks and VPCs in any AWS Region. AWS VPN CloudHub enables connectivity between on-premises networks using AWS Direct Connect or a VPN within the same Region. The VIF is associated with the VGW directly. Existing AWS VPN CloudHub functionality will continue to be supported. You can attach an AWS Direct Connect virtual interface (VIF) directly to a virtual private gateway (VGW) to support intra-Region AWS VPN CloudHub. Q: What type of traffic is, and is not, supported by AWS Direct Connect gateway? Please refer to AWS Direct Connect User Guide to review supported and not supported traffic patterns. Q: I currently have a VPN in us-east-1 attached to a virtual private gateway (VGW). I want to use AWS VPN CloudHub in us-east-1 between the VPN and a new VIF. Can I do this with AWS Direct Connect gateway? No, you cannot do this with an AWS Direct Connect gateway, but the option to attach a VIF directly to a VGW is available to use the VPN <-> AWS Direct Connect AWS VPN CloudHub use case. 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? No, an existing private virtual interface associated with VGW cannot be associated with an AWS Direct Connect gateway. 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. 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? Yes, as long as the VPC route table has routes to the virtual private gateway (VGW) towards the VPN. Q: Can I attach a virtual private gateway (VGW) to an AWS Direct Connect gateway if it is not attached to a VPC? No, you cannot associate an unattached VGW to AWS Direct Connect gateway. Q: I have created an AWS Direct Connect gateway with one AWS Direct Connect Private VIF, and three non-overlapping virtual private gateways (VGWs) -- each associated with a VPC. What happens if I detach one of the VGW from the VPC? 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. 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? Traffic from your on-premises network to the detached VGW (associated with a VPC) will stop. 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? No, AWS Direct Connect gateway's only support routing traffic from AWS Direct Connect VIFs to VGW (associated with VPC). In order to send traffic between two VPCs, you must configure a VPC peering connection. Q: I currently have a VPN in us-east-1 that is attached to a virtual private gateway (VGW). 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? No, an AWS Direct Connect gateway will not route traffic between a VPN and an AWS Direct Connect VIF. To enable this use case, you must create a VPN in the AWS Region of the VIF and attach the VIF and the VPN to the same VGW. Q: Can I resize a VPC that is associated with an AWS Direct Connect gateway? Yes, you can resize the VPC. If you resize your VPC, you must resend the proposal with the resized VPC CIDR to the AWS Direct Connect gateway owner. Once the AWS Direct Connect gateway owner approves the new proposal, the resized VPC CIDR will be advertised towards your on-premises network. Q: Is there a way to configure an AWS Direct Connect gateway to selectively propagate prefixes to/from VPCs? Yes, AWS Direct Connect gateway offers a way for you to selectively announce prefixes towards your on-premises networks. 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. If you want to limit traffic to
and from any specific VPC, you should consider using Access Control Lists (ACLs) for each VPC.
