Abstract

A router comprises a route resolution module to maintain routing information in accordance with a topology of a network, and an indirect next hop manager to maintain indirect next hop data that associates protocol next hops with forwarding next hops. The route resolution module invokes an application programming interface (API) of the indirect next hop manager for associating and disassociating protocol next hops and forwarding next hops. In response to a network event, the route resolution module can modify the indirect next hop data to reduce the time and resources necessary to perform route resolution.
