Traditional network layer packet forwarding relies on the information provided by network layer( )protocols, or static routing, to make an independent forwarding decision at each( )within the network. The forwarding decision is based solely on the destination( )IP address. All packets for the same destination follow the same path across the network if no other equal-cost( )exist. Whenever a router has two equal-cost paths toward a destination, the packets toward the destination might take one or both of them, resulting in some degree of load sharing. Enhanced Interior Gateway Routing Protocol (EIGRP) also supports non-equal-cost( )sharing although the default behavior of this protocol is equal-cost. You must configure EIGRP variance for non-equal-cost load balancing.问题1选项A.switchingB.signalingC.routingD.session问题2选项A.switchB.hopC.hostD.customer问题3选项A.connectionB.transmissionC.broadcastD.customer问题4选项A.pathsB.distanceC.broadcastD.session问题5选项A.loanB.LoadC.contentD.constant

解析
传统的网络层分组转发是根据网络层路由协议或者静态路由提供的信息,在网络中的每一跳都做出一个独立的转发决策。转发决策只是基于目标单播地址而做出的。如果没有相等费用的其他通路存在,朝着同一目标的所有分组都遵循网路中的同样路径。当路由器具有通向同一目标的相等费用的两条通路时,流向目标的分组就可能走两条通路中的任何一条,这就产生了同样程度的负载共享。增强的内部网关路由协议(EIGRP)也支持不等费用的负载共享,虽然这个协议默认的行为是相等费用的负载共享。通过配置,你可以把EIGRP变为不等费用的负载共享方式。
