Abstract
A network may include a first customer edge (CE) router and a second CE router. The first CE router may run an external border gateway protocol (EBGP) to exchange routing information with a first provider edge (PE) router that is in a first multi-protocol label switching (MPLS) network and may run an interior gateway protocol (IGP) to exchange routing information with the second CE router. The second CE router may run the IGP to exchange routing information with the first CE router and may run the EBGP to exchange routing information with a second PE router in a second MPLS network.
