RIP(Routing Information Protocol)是最常使用的内部網關協議(InteriorGateway Protocol)之一(yī),是一(yī)種典型的基于D-V 算法的動态路由協議。通過UDP(User Datagram Protocol)報文交換路由信息,使用跳數(HopCount)來衡量到達目的地的距離(lí)(被稱爲路由權-Routing cost)。由于在RIP 中(zhōng)大(dà)于或等于16 的跳數被定義爲無窮大(dà)(即目的網絡或主機不可達),所以RIP 一(yī)般用于采用同類技術的中(zhōng)等規模的網絡,如校園網及一(yī)個地區範圍内的網絡,RIP 并非爲複雜(zá)、大(dà)型的網絡而設計。
啓動RIP,進入RIP 視圖: router Rip關閉RIP: no rip在指定的網絡上使能RIP network{ network-number| all }在指定的網絡上禁用RIP no network{ network-number| all
