Associate multiple transit gateways in the same AWS Region

[alexsandro-ramos]

Dear,

I can’t find aws documentation explaining about the posibility of associate multiple transit gateway int the same region. For me until now is only possible have one transit gateway per region.

The question about my doubt is below.

A multinational bank has a single transit gateway that has multiple VPC and VPN attachments. The Network team established an AWS Direct Connect connection from the company’s on-premises network to a Direct Connect location. Afterward, they provisioned an AWS Direct Connect Gateway that connects to the AWS Direct Connect location via a transit virtual interface.

With this setup, what other network connections can be implemented? (Select TWO.)

Answers

Connect multiple VPCs in the same or different AWS account using the Direct Connect connection.

Associate multiple transit gateways in the same AWS Region.

Thank you!

Hello alexsandro,

It’s possible to associate up to 3 transit gateways in the same AWS Region using a transit virtual interface connected to a DX.

Hope this clarifies.
