实验07IGRP非等值带宽的负载平衡

1、实验七 通过igrp路由协议实现非等值带宽的负载平衡实验要求：通过在两台路由器上配置igrp路由协议实现路由器之间非等值带宽的负 载平衡。实验拓扑：路由器r1配置如下:router > en进入特权模式router # conf t进入全局配置模式router #host rl更改路由器名rl (config)# int lol进入了 loopback 1 口rl (config-if)# ip add 1.1.1.1 255.255.255.0rl (config-if)# az直接退z特权模式r1 #config tr1 (config)# int s()配置so url (conf

2、ig-if)# ip add 2.2.2.1 255.255.255.0配置iprl (config-if)# clock rate 56000配置dce端吋钟r1 (config-if)# no shut启用端口rl (config-if)#exitr1 (config)# router igrp 100启用igrp路由协议r1 (config-router)# net 1.0.0.0.0加入直连的网络号r1 (config-router)# net 4.0.0.0rl (config-router)# net 2.0.0.0rl (config-router)#variance 6设置va

3、riance值,可以在路径间启用负载平衡，把值设成6的依据是用低速带宽的metric值除高速带宽的 metric值，如何看到低速带宽的metric值呢（因路由表缺省只显示最优路由）？把高 速带宽的端口禁用，就町看到低速带宽的metric值了rl # debug ip icmp路由器r2配置如下:router> enrouter# config trouter (config)# host r2r2 (config-if)# int sor2 (config-if)# ip add 2.2.2.2 255.255.255.0r2 (config-if)# no shutr2 (config

4、-if)# exitr2 (config)# int lolr2 (config-if)# ip add 4.4.4.2 255.255.255.0r2 (config-if)# exitr2 (config)# router igrp 100r2 (config-router)# net 3.0.0.0r2 (config-router)# net 4.0.0.0r2 (config-router)# net 2.0.0.0r2 (config-router)# variance 6router # debug ip iemp三.实验结果:rlttpingprotocol ip:target
