EIGRP配置实战

 

需求一：如图。全网运行EIGRP，关闭自动汇总，除了R2环回接口2.2.2.2/24在EIGRP10中运行,其他路由器的直连接口和loopback接口均network到EIGRP100中;

需求二:完成以上配置后,在R1/2/4上观察是否有关于172.16.0.0 的5条详细路由,如果有,请把他们汇总成为一条172.16.0.0/21的汇总路由条目;

需求三:在R1上观察到34网段是否有2个下一跳,手工在R1的S0/0上,将延迟配置为150,

再次观察是否还有两个下一跳,配置variance,使R1实现非等价负载均衡,再次观察R1是否又变成两个下一跳;

需求四:在R3上观察,是否能够收到2.2.2.2的路由为什么,怎样配置才能收到该路由;
