RIP 路由协议的配置一、实验目的1、复习路由器的三种模式及口令管理2、练习RIP 动态路由协议的基本配置；3、掌握了解RIP 路由协议原理二、实验环境：Cisco Packet Tracer三、关于RIP 的基础知识RIP（Routing Information Protocol）是最常使用的内部网关协议(Interior Gateway Protocol)之一，是一种典型的基于D-V 算法的动态路由协议。

通过UDP（User Datagram Protocol）报文交换路由信息，使用跳数（Hop Count）来衡量到达目的地的距离（被称为路由权－Routing cost）。

由于在RIP 中大于或等于16 的跳数被定义为无穷大（即目的网络或主机不可达），所以RIP 一般用于采用同类技术的中等规模的网络，如校园网及一个地区范围内的网络，RIP 并非为复杂、大型的网络而设计。

启动RIP，进入RIP 视图：router Rip关闭RIP：no rip在指定的网络上使能RIP network{ network-number| all }在指定的网络上禁用RIP no network{ network-number| all四：实验步骤：绘制拓扑图如下所示(为每个路由器添加一个WIC-2T模块)：配置过程：Router1：Router>enable //进入特权模式Router#conf ter //进入全局配置模式Enter configuration commands, one per line.
