计算机网络RIP路由配置实验

1、实验名称RIP路由配置实验实验日期2018年11月2日实验目的（1）掌握在路由器上配置RIP的方法；（2）分析RIP路由协议；（3）调试RIP路由协 议实验内容配置路由R1,R2,R3各个接口的路由接口的IP地址，每个路由器上配置RIP路由 协议，然后路由与邻居交换完整的路由表，收到邻居发来的路由表之后，更新自己的 路由表RIP使用UDP协议，端口号520,使用组播地址邻居每30秒发送自己完整的路 由表。RIP存在坏消息传播得慢的问题，如下图所示，当R3路由器f0/1端口关闭之 后，经过若于次路由表交换之后，才发现不可达。一、实验原理路由与邻居交换完整的路由表，收到邻居发来的路由表之后，更新自

2、己的路由表。RIP使用UDP 协议，端口号520，使用组播地址邻居每30秒发送自己完整的路由表。RIP存在坏消息传播得慢的 问题，如下图所示，当R3路由器f0/1端口关闭之后，经过若于次路由表交换之后，才发现 不可达。RIPv2的报文格式:Csmnajidfl)Versi-on(l)unused Address JamiJyef (2)R-sutt Tag (2)IP addre ss (4)Subnet mask (T)hfext Hop4,Mrtri g (4)RIP Tsiqxi 2 的报文裕式其中：.Metric:到下一路由器的权值。.NextHop:下一驿站，可以对使用多路由协议的网

3、络环境下的路由进行优化.Subnet mask:子网掩码，应用于IP地址产生非主机部分地址，为0时表示不包括子网掩码 部分，使得RIP能够适应更多的环境。.Ip Address:地址域，包括网络类和IP地址在内，RIP报文中对每一网络共有14个字节的 地址空间。.RouteTag:外部路由标记。它提供一种从外部路由中分离内部路由的方法，用于传播从外部路 由器协议(EGP)获得的路由信息。.Address F amily Identifier :指示路由页中的地址种类，这里应为2.Version:版本号域包括生成R I P报文时所使用的版本。在此为2.Command:命令域指出RIP报文是一个请
