实验图：
实验目的：验证rip v1 与 rip v 2 的不同。
实验步骤：（首先使用rip v 2 ,但不关闭自动汇总。）

使用rip v1版本重复实验：

步骤：
将ver 2 去掉就行啦！
++++++++++++++++++++++++++++++++++++++++++++++++++
不管你信不信，路由表真他X的与rip v2不打no au 一模一样。
不信你看：

你会说我是复制的吧！你看看时间。
你会说那把rip 1 也关闭自动汇总啊！不行啊！rip1 真他X的不知道可变长的子网掩码。关了也不行。
可见RIP V2 只不过多了no auto-summary 这条命令罢了。不打这条命令，你也别起RIP V2啦！
