本实验对RIP进行基本的配置，涉及到配置RIP所必须的命令和常用的监测命令。
1.实验目的 通过本实验，读者可以掌握以下技能:
在器上启动RIP;
声明相应网络进入RIP路由进程;
查看路由表并理解相关字段含义;
查看RIP协议配置信息;
监测RIP协议相关信息。
2.设备需求 本实验需要以下设备:
路由器3台，分别命名为R1、R2和R3，均要求具有1个以太网接口和2个串行接□;
3条DCE电缆和3条DTE电缆，或3条DCE转DTE电缆;
1台终端，如 2509路由器。及用于反向Telnet的相应电缆;
1台带有超级终端程序的PC机，以及Console电缆及转接器。
3.拓扑结构及配置说明 本实验拓扑结构如图5.1所示，首先把DCE电缆和DTE电缆进行对接，共组成3对电缆。然后用这3对电缆把R1和R2"RE和R3、R2和R3分别连接起来。各路由器使用的接口及其编号见图5.1中的标注。
IP地址分配如下:
R1: E0 172.16.1.1, 50 172.16.12.1, 51 172.16.13.1;
R2: E0 172.16.2.2, 50 172.16.12.2, 51 172.16.23.2;
R3: E0 172.16.3.3, 50 172.16.13.3, 51 172.16.23.30
子网掩码均为 255.255.255.00
实验中R、R2之间和R、R3之间的串行线路速率设置为5OOkbit/s;R2、R3之间的串行线路速率设置为64kbit/s。
本实验要求通过对RIP路由选择协议的配置，实现全网的连通。
4.实验配置及监测结果 实验环境准备就绪后，打开PC机、访问和路由器的电源。开始进行实验。
现在假设我们不知道各路由器串行接口所连接的电缆是DCE电缆还是DTE电缆，同时路由器的E0接口均没有连接任何设备。在这样的基础上开始配置3台路由器，并启动RIP路由选择协议。
具体配置过程如配置清单5-1、5-2所示，配置清单后有详细的讲解。
