Abstract
A method and an apparatus to select a route in a network device within a networked system have been disclosed. In one embodiment, the method includes receiving at a router in a Border Gateway Protocol (BGP) network a first route entry via local redistribution from a first protocol to BGP and a second route entry from a peer router coupled to the router via the network, wherein the first route entry is received earlier than the second route entry. The method may further include downloading administrative distances of the first and the second route entries to a route information base (RIB) of the router and redistributing the administrative distances from the RIB to a BGP table maintained by a BGP module of the router. In some embodiments, the method further includes selecting one of the first and the second route entries based on their administrative distances.
