A system may include a first customer edge (CE) router that is included in a customer network and is connected to a first provider edge (PE) router in a first multi-protocol label switch (MPLS) network, the first CE router configured to communicate with the first PE router using an external border gateway protocol (EBGP). The system may also include a second CE router that is included in the customer network and is connected to a second PE router in a second MPLS network. The second CE router may be configured to exchange routing information with the second PE router based on the EBGP and distribute routing information to the first CE router based on an interior gateway protocol (IGP). The system may also include a third CE router that is included in a first local network and is connected to a third PE router in the first MPLS network, the third CE router configured to exchange routing information with the third PE router.

Interconnecting multiple MPLS networks

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.
