Each associated PE router maintains aseparate IP forwarding table for each VPRN. Additionally, the PE routers exchangethe routing information configured or learned from all customer sites via MP-BGPpeering. Each route exchanged via the MP-BGP protocol includes a RouteDistinguisher (RD), which identifies the VPRN association.
