Creating VPC Attachments to the Enterprise Router

Scenarios

This section describes how to attach VPCs to the enterprise router and configure routes.

Procedure

1. Attach the two VPCs to the enterprise router.

   For details, see Creating VPC Attachments to the Enterprise Router.

   Default Route Table Association and Default Route Table Propagation are enabled when you create the enterprise router. After VPCs are attached to the enterprise router, the system will automatically:

   • Associate the VPC attachment with the default route table of the enterprise router.
   • Propagate the VPC attachment to the default route table of the enterprise router. The route table automatically learns the VPC CIDR block as the destination of routes.

2. Add routes to VPC route tables for traffic to route through the enterprise router.
