问题 The Border Gateway Protocol (BGP)is an interautonomous system(  )protocol.The primary function of a BGP speaking system is to exchange network (  )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 (  )interdomain routing.These mechanisms include support for advertising an IP (  )and eliminate the concept of network class within BGP.BGP-4 also introduces mechanisms that allow aggregation of routes, including (  )of AS paths.These changes provide support for the proposed supernettting scheme. 问题1选项A.connectingB.resolvingC.routingD.supernettting问题2选项A.SecubilityB.reachabilityC.capabilityD.reliability问题3选项A.AnswerlessB.ConnectionlessC.ConfirmlessD.classless问题4选项A.prefixB.suffixC.infixD.reflex问题5选项A.reservationB.relationC.aggregationD.connection

解析 边界网关协议BGP是自治系统间的路由协议。BGP发布系统的基本功能就是与其他BGP系统交换网络可到达性信息。这种网络可到达性信息包含了可到达性信息穿越的自治系统的列表。BGP-4提供了一系列新的机制来支持无类别的域间路由。这些机制包括支持发布IP前缀,从而在BGP中排除了网络类别的概念。BGP-4也引入了路由聚合机制,包括AS通路的聚合。这些改变提供了对提议的超网方案的支持。
