什么是动态路由 § 网络中的路由器之间相互通信，传递路由信息，利用收到的路由信息更新和维护路由表的过程 § 基于某种路由协议实现的 v 动态路由的特点 § 减少管理任务 § 占用网络带宽 动态路由协议 v 动态路由协议 § 向其他路由器传递路由信息 § 接收其他路由器的路由信息 § 根据收到的路由信息计算出到每个目的网络的最优路径，并由此生成路由表 § 根据网络拓朴变化及时调整路由表，同时向其他路由器宣告拓朴改变的信息
RIP v1路由协议的配置 v 启动RIP进程 Router(config)# router rip v 宣告主网络号 Router(config-router)# network network-number
验证配置 v 查看路由表 Router# show ip route v 查看路由协议配置 Router# show ip protocols v 打开RIP协议调试命令 Rouetr# debug ip rip
RIP v1路由协议配置实例 RouterA(config)#interface f0/0 RouterA(config-if)#ip address 192.168.1.1 255.255.255.0 RouterA(config-if)#no shutdown
