CCNA配置试验之二 RIPv2协议的配置

RIP 概述 RIP 也称距离矢量协议，用信息包所经过的网关来做距离的单位，超过15 跳便无法到达 RIP 是通过UDP 端口520 来进行操作的,RIP 信息包是封装在UDP segment 中的.RIP 定义了2 种信息类型 Request message( 请求信息) 和Response message( 应答信息). 请求信息是用来向邻居请求发送一个update( 更新), 应答信息运载着这个被请求的update. RIP 的 metric 是基于hop count( 跳数) 的,metric 为16 代表不可达 RIPv2 与 RIPv1 的区别 - 是个无类的路由协议 - 组播（224.0.0.9 ）路由更新（不用广播） - 支持 VLSM （在更新过程中发送掩码） - 支持手动汇总 - 支持 (MD5) 或者 纯文本认证 RIP 配 置 Router(config)#router rip 激活RIP协议 Router(config-router)# version 2 启用RIPv2 Router(config-router)#network network-number 选择需要激活的接口所在的网段 用试验验证RIPv2的配置： 试验环境如下： 试验环境说明: R1的ip地址为10.1.1.1 (S0/0) 网络掩码为255.255.255.0 R2的ip地址为 10.1.1. 2 (S0/0) 10.2.2.2 （S0/1） 网络掩码为255.255.255.0 R3的ip地址为 10.2.2.3 (S0/1) 网络掩码为255.255.255.0 R1的S0/0 R2的S0/1 为DCE端 试验要求：在路由器间配置RIPv2 使路由器间相互ping通。 下面开始试验（红色字体为配置内容） R1 Router>en Router#conf t Enter configuration commands, .e per line.
