cisco路由器基本实验之三 动态路由之RIP协议的配置（Boson NetSim）

言归正传，Boson Netsim的实验规划，默认路由下一个实验应该是RIP协议的配置。众所周知，RIP（Routing Information Protocol），即路由信息协议，它与IGRP，OSPF等一样都是属于IGP（Interior Gateway Protocol）――内部网关协议，它是一种历史很悠久的协议了，但是迄今为止，RIP还在小型网络中很流行，因为它是基于跳数来对路径进行度量的（仅仅只靠跳数来进行度量也成为了RIP为人所诟病的地方），这样使得RIP相比之下显得最简单，并且大多数的路由器也都支持RIP。据说，RIP还可以保证不同厂商的路由器互联时能有良好的兼容性。下面再说说RIP的大概工作机理。
　　RIP把每经过一个路由器称为经过了一跳，而每经过一跳，RIP就会将他的度量值（metric）加1，这样的话，跳数越多的则路径越长，而RIP会优先选择一条到达目标网络跳数少的路径，他支持的最大跳数是15跳，超过则被认为是不可达。接下来看看我的实验。



顺便说一下，在最近几次的实验中，我都将以这幅图作为实验的拓扑图。和前两次一样，关键语句我都有注解，一来这样方便想学习的朋友，二来也可以作为我自己以后备查，呵呵，下面看看我的配置：
