The Border Gateway Protocol(BGP)is an interautonomous system【S1】protoco1．The primary function of a BGP speaking system is to exchange network【S2】information withother BGP system．This network reachability information includes information on the list of Auton0．mous System(ASs)that reachability information traverses．BGP一4 provides a new set of mecha-nisms for supposing【S3】interdomain routing．These mechanisms include support for adver-tising an IP【S4】and eliminate the concept of network class within BGP．BGP-4 also intro-duces mechanisms that allow aggregation of routes，including【S5】of AS paths．These chan-ges provide support for the proposed supernettting schem

【S1】

A．connecting

B．resolving

C．routing

D．supernettting

参考答案:

C解析：BGP(Border-Gateway Protocol，边界网关协议)是用来连接Intemet上的独立系统的路由选择协议。它是Internet工程任务组制定的一个加强的、完善的、可伸缩的协议。BGP4支持cIDR寻址方案，该方案增加了Internet上的可用IP地址数量。BGP是为取代最初的外部网关协议EGP设计的。它也被认为是一个路径矢量协议。BGP fBorder Gateway Protocol)是一种在自治系统之间动态交换路由信息的路由协议。一个自治系统的经典定义是在一个管理机构控制之下的
