Abstract: Methods and apparatuses are disclosed for configuring a Provider Backbone Bridge (PBB) interface within Virtual Private LAN Service using Multi-Protocol Border Gateway Protocol (MP-BGP). Previously, the only ways to enable PBB interfaces for transmission were by learning, which poses security and scalability concerns due to flooding, or by manual configuration, which is impractical for large networks. Embodiments of the present invention enable custom topologies to be built in a controlled manner, which has not previously been possible for PBB over VPLS. By using MP-BGP messages to exchange PBB interface information between nodes, peering relationships are established, and communities may be built with any desired topology. Previously, PBB has only been used as a connectionless bridge; embodiments of the present invention use PBB as a connection between edge nodes. Network designers are provided increased flexibility, and security and congestion are improved, benefiting end users.

Abstract: A router maintains routing information including (i) route data representing destinations within a computer network, (ii) next hop data representing interfaces to neighboring network devices, and (iii) indirect next hop data that maps a subset of the routes represented by the route data to a common one of the next hop data elements. In this manner, routing information is structured such that routes having the same next hop use indirect next hop data structures to reference common next hop data. In particular, in response to a change in network topology, the router need not change all of the affected routes, but only the common next hop data referenced by the intermediate data structures. This provides for increased efficiency in updating routing information after a change in network topology, such as link failure.
