实验 9 RIP 路由协议配置

一．实验目的：

掌握 RIP 动态路由协议的配置、诊断方法。

二．实验要点：

1．配置 RIP 动态路由协议，使得两台 Cisco2611 路由器模拟远程网络互联。

2．对运行中的 RIP 动态路由协议进行诊断。

三．实验设备：

路由器 Cisco 2621 两台，带有网卡的工作站 PC 两台，控制台电缆一条，交叉双绞线若干。

四、实验环境



图 9

纠正一下，PC0的网关为192.168.0.1，PC1的网关为192.168.1.1

五. 实验步骤

1．按图 9 连接路由器和各工作站。

2．按图 9 配置路由器和各工作站 IP 地址等参数。

3．配置路由器 RouterA 和 RouterB 上的 RIPv1 协议。（RouterA、RouterB对应实验截图中的Router0、Router1）

路由器 A 的 RIP 协议配置

RouterA(config)#router rip

RouterA(config-router)#net 10.0.0.0

RouterA(config-router)#net 192.168.0.0

路由器 B 的 RIP 协议配置

RouterB(config)#router rip

RouterB(config-router)#net 10.0.0.0

RouterB(config-router)#net 192.168.1.0

4．测试各工作站之间的连通性。

问题：主机 A 是否能 ping 通主机 B 答案：能

5．检查路由器 RouterA 和 RouterB 的路由表。

6．检查路由器 RouterA 和 RouterB 的运行配置文件内容。

7．打开对 RIP 的诊断，使用 shutdown 和 no shutdown 命令关闭、开启串行接口 Serial 0/0、

快速以太网接口 Fastethernet 0/0。观察 RIP 诊断的输出。

RouterA#show ip protocols //显示路由器上配置的动态路由协议信息

RouterA#show ip rip //显示 RIP 当前运行状态及配置信息

RouterA#debug ip rip //可以显示 RIP 的所有活动，显示接收和发送的接口，更新信息的 RIP 版本及每条路由的度量

六. 实验总结

1．路由表的作用

2．从 RIP 的诊断信息中分析 RIP 的特性，如 RIP 的路由更新周期等。

具体操作步骤：

当没有配置RIP时，Router0和Router1无法相互ping通

在Router1中配置：

Router>enable
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface Serial0/0
Router(config-if)#ip address 10.0.0.2 255.0.0.0
Router(config-if)#clock rate 64000
This command applies only to DCE interfaces
Router(config-if)#no shutdown
Router(config-if)#
