实验开始前，先说点与实验无关的事情，在前两篇路由配置的文章中，有很多的网友参与进来进行讨论，有非51cto的网友，也有51cto的朋友，在这里要感谢一下gairuhe朋友，他多次提出意见，建议我使用可以使用真正的IOS来进行实验模拟的Dynamips软件，并且建议我在文章中把路由表也贴出来，这样会看得更加直观和方便，这些建议都很好，在此谢谢众多网友的支持！
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：
