Question

A company uses transit gateways to route traffic between the company's VPCs. Each transit gateway has a single route table. Each route table contains attachments and routes for the VPCs that are in the same AWS Region as the transit gateway. The route tables in each VPC also contain routes to all the other VPC CIDR ranges that are available through the transit gateways. Some VPCs route to local NAT gateways. The company plans to add many new VPCs soon. A network engineer needs a solution to add new VPC CIDR ranges to the route tables in each VPC. Which solution will meet these requirements in the MOST operationally efficient way?

Accepted Answer

Update the route tables in each VPC to use the new prefix list ID as the destination and the appropriate transit gateway ID as... AWS Transit Gateway centrally connects many VPCs and on-premises networks at scale.
