RIP（Routing Information Protocol）是最常使用的内部网关协议(InteriorGateway 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
