EIGRP实验

一、现根据课本的所给拓扑图将设备连接好； 二、根据书本所给的拓扑图，将设备相应的端口、IP地址配好（当然这之前要将路由器原来的配置文件给删除，并重启），配置好网络； 三、最后用ping命令来检验所配置网络的连通性。 四、关键配置步骤、命令： （一）eigrp配置 拓扑图： 根据拓扑图，将整个网络配置好，包括ip，端口地址，这些个过程书上有，这里略了。下面是网络配好后用一些命令来查看一些配置及状态： 1.在Westasman上使用show ip interfaces命令，显示其接口或者是IP地址的up或者down状态；

2.在Westasman上使用show ip eigrp neighbors命令，来查看邻居表，检查EIGRP是否与其邻居建立邻居关系。 3.在Westasman上使用show ip eigrp topology命令，来显示目标网络192.168.200.0/24的拓扑表。 5.在Westasman上使用show ip eigrp traffic命令
