Add a route to a transit gateway route table using Amazon VPC Transit Gateways

To route traffic between the peered transit gateways, you must add a static route to the transit gateway route table that points to the transit gateway peering attachment. The owner of the accepter transit gateway must also add a static route to their transit gateway's route table.

To create a static route using the console

  1. Open the Amazon VPC console at https://console.amazonaws.cn/vpc/.

  2. On the navigation pane, choose Transit Gateway Route Tables.

  3. Select the route table for which to create a route.

  4. Choose Actions, Create static route.

  5. On the Create static route page, enter the CIDR block for which to create the route. For example, specify the CIDR block of a VPC that's attached to the peer transit gateway.

  6. Choose the peering attachment for the route.

  7. Choose Create static route.

To create a static route using the Amazon CLI

Use the create-transit-gateway-route command.

Important

After you create the route, associate the transit gateway route table with the transit gateway peering attachment. For more information, see Associate a transit gateway route table using Amazon VPC Transit Gateways.
