The Border Gateway Protocol（BGP）is an interautonomous system（在此空作答）protocol.The primary function of a BGP speaking system is to exchange network（72）information with other BGP system.This network reachability information includes information on the list of Autonomous System（ASs）that reachability information traverses.BGP-4 provides a new set of mechanisms for supporting（73）interdomain routing.These mechanisms include support for advertising an IP（74）and eliminate the concept of network class within BGP.BGP-4 also introduces mechanisms that allow aggregation of routes,including（75）of AS paths.These changes provide support for the proposed supernetting scheme.
