RIP【Routing Information Protocol】路由信息协议,它是一种基于矢量(Distance-Vector)算法的协议,使用跳数作为度量来衡量到达目的网络的距离,RIP主要应用于规模较小的网络中,缺点:古老、收敛速度很慢
运行原理如下:
- 路由器每 30秒会与相邻的路由器交换路由表数据包,以动态的建立路由表,如果240秒没有收到对方消息,就将对方的路由表从自身删除
- RIP只看距离远近,距离是以跳数(经过路由器的个数)来衡量
- RIP 允许最大的hop数(跳数)为15----->多于15跳不可达
- 路由协议如下:
网络拓扑图如下:运用 RIP 动态路由协议来实现所有PC网络互相通信(如想要禁止某网段访问可直接在RIP中不进行宣告即可)
实现方法如下:
