AWS Direct Connect gateway allows you to access any AWS Region (except China) using your AWS Direct Connect connections. You can associate up to three Transit Gateways from any AWS Region with each Direct Connect gateway. AWS Direct Connect is introducing a new type of virtual interface called the transit virtual interface to support connectivity to AWS Transit Gateway. You can create a transit virtual interface using your 1/2/5/10 Gbps AWS Direct Connect connections at any AWS Direct Connect locations, with the exception of AWS Direct Connect locations in China. To increase the resiliency of your connectivity, we recommend that you attach at least two transit virtual interfaces from different AWS Direct Connect locations, to the Direct Connect gateway. For more information, please refer to the AWS Direct Connect resiliency recommendation.

AWS Direct Connect support for AWS Transit Gateway is now available in US East (N. Virginia), US East (Ohio), US West (N. California), and US West (Oregon) AWS Regions. Support for other AWS Regions is coming soon. For more information about AWS Direct Connect support for AWS Transit Gateway, please read the user guide.
