BGP-signaled VPLS

In a BGP-signaled VPLS environment, each VPLS on each PE must be assigned a unique route target. The route target must be the same for a particular VPLS across all PEs that belong to the VPLS. The route target is the VPLS ID for a BGP-signaled VPLS.

Also, each PE must be assigned a unique site identifier. The site identifier is the same as the virtual edge identifier (VEID) that is defined in RFC 4761.

ForwarderEndpoints are peers only when they share complementary incoming VC ID and outgoing VC ID values. That is, the incoming VC ID for the one is the outgoing VC ID for the other, and the outgoing VC ID for the one is the incoming VC ID for the other.
