一、实验题目RIP
二、实验设备
CISCO路由器、专用电缆、网线、CONSOLE线、PC机
三、实验内容
在CISCO 路由器上配置RIP
观察、分析现象，了解RIP 的工作原理
四、原理
RIP（RoutinginformationProtocol）是应用较早、使用较普遍的内部网关协议（InteriorGatewayProtocol,简称IGP），适用于小型同类网络，是典型的距离向量（distance-vector）协议。
文档见RFC1058、RFC1723。
RIP通过广播UDP报文来交换路由信息，每30秒发送一次路由信息更新。
RIP提供跳跃计数（hopcount）作为尺度来衡量路由距离，跳跃计数是一个包到达目标所必须经过的路由器的数目。
如果到相同目标有二个不等速或不同带宽的路由器，但跳跃计数相同，则RIP认为两个路由是等距离的。
RIP最多支持的跳数为15，即在源和目的网间所要经过的最多路由器的数目为15，跳数16表示不可达。
RIPv2由RIPv1而来，属于RIP协议的补充协议，主要用于扩大RIP2信息装载的有用信息的数量，同时增加其安全性能。
RIP2是一种基于UDP的协议。
在RIP2下，每台主机通过路由选择进程发送和接受来自UDP端口520的数据包。
