Zusammenfassung:	A method is disclosed for providing context-based routing table updates in Border Gateway Protocol (BGP) hosts. One or more contexts representing distinct routing tables are defined in a BGP host. As part of establishing a BGP session, a particular context of the one or more contexts is advertised to the BGP peer. In response to receiving from the BGP peer a route update message that includes information identifying the particular context, the routing table that is represented by the particular context is updated at the BGP host.
