RIP Version 2路由协议路由协议 【实验目的】 掌握在路由器和三层交换机上配置RIP V2。【背景描述】 假设校园网通过一台路由器连接到校园外的另一台路由器上，现要在路由器上做适当配置，实现校园网内部主机与校园网外部主机的相互通信。 本实验以2台R2624路由器为例，路由器分别为Router1和Router2，路由器之间通过串口采用V35 DCE/DTE电缆连接。将电缆的DCE端连接到Router1的串口Serial 0上，PC1的IP地址和缺省网关分别为172.16.1.11和172.16.1.1，PC2的IP地址和缺省网关分别为172.16.3.22和172.16.3.2，网络掩码都是255.255.255.0。【实现功能】 实现网络的互连互通，从而实现信息的共享和传递。 【实验拓扑】【实验设备】 R2624（2台）、V35DCE（1根）、V35DTE（1根） 【实验步骤】在路由器Router1上配置接口的IP地址和串口上的时钟频率，输入如下代码：Router1(config)# interface fastethernet 0 ！进入接口F0的配置模式Router1(config-if)# ip address 172.16.1.1 255.255.255.0 ！配置路由器接口F0的IP地址Router1(config-if)# no shutdown ！开启路由器fastethernet0接口!Router1(config)# interface serial 0 ！进入接口S0配置模式Router1(config-if)# ip address 172.16.2.1 255.255.255.0 ！配置路由器接口S0的IP地址Router1(config-if)#clock rate 64000 ！配置Router1的时钟频率（DCE）Router1(config-if)# no shutdown ！开启路由器serial 0接口验证测试：验证路由器接口的配置验证测试：验证路由器接口的配置 Router1#show ip interface brief 显示如下：显示如下：Interface IP-Address OK?
