使用EIGRP的监测和诊断命令(1)

　　有一些Show和Debug命令是监测和诊断EIGRP协议的配置时常用的，熟悉这些俞令，将有利于对EIGRP进行配置和排障。本节对这些命令进行演示和讲解。

　　1.实验目的

　　通过本实验，读者可以掌握以下技能

　　查看EIGRP的流量信息;

　　查看EIGRP拓扑信息，

　　监测EIGRP相关信息。

　　2.设备需求及拓扑结构

　　本实验是在实验1配置成功的基础上进行的，设备和拓扑结构与实验1完全相同。为了阅读上的方便，现将拓扑结构图复制到这里，见图6-2。

　　3.实验配置及监测结果

　　本实验主要演示show ip eigrp topoTogy、show ip eigrp traffic、debug ip eigrp和debug eigrp　packet等命令的用法和输出结果。

　　监测清单6-2记录了实验的全过程，随后有对相应内容的讲解。
