Cloud Enterprise Network (CEN) supports route advertisement. You can advertise routes of virtual private clouds (VPCs) and virtual border routers (VBRs) to a CEN instance so that other network instances attached to the CEN instance can learn these routes.

Background information

The following table describes the routes that can be advertised to CEN instances.
Note The CEN console allows you to advertise only VPC routes to CEN. To advertise VBR routes to CEN, you must call the PublishRouteEntries API operation. For more information, see PublishRouteEntries.
