OSPF with BGP/MPLS VPN backbone

Summary[edit]

Description
English: Diagram of using OSPF as the routing protocol between a service provider's BGP/MPLS VPN backbone and a customer. The service provider's equipment is labeled as PE (provider edge) and the customer's equipment is labeled as CE (customer edge). The boxes represent different sites within the customer's network. Area 0 is multi-homed with two PEs. Area 1 is single-homed, and the PE acts as an area border router (ABR) between area 1 and area 0. Area 2 comprises two different sites, each with its own PE ABR, but also an internal backdoor link which is the preferred link between the two sites rather than the service provider's network. Area 3 is similar to area 2, but is also a configured with a sham link by the service provider. A sham link is required if the preferred link between the two sites is the service provider and not the backdoor link.
