Abstract
According to one aspect of the present invention, a method includes obtaining a first advertisement at a first provider edge (PE) device from a first customer edge (CE) device that is associated with a virtual private network, and sending a second advertisement on a control plane path associated with a border gateway protocol after obtaining the first advertisement. The first PE device has a routing and forwarding table. The first advertisement identifies a plurality of local routes associated with the first VPN, and includes a first indication that information relating to the plurality of local routes is not to be stored in the routing and forwarding table. The second advertisement identifies the local routes, an address of the first CE device, and the first CE device as a next hop.
