@根据拓扑图，实现PC端通交换机ping通路由器loop back地址TOC

实现PC端通交换机ping通路由器loop back地址

一. 拓扑图

二、要求
作业要求：
1、AR3上的loopback0 x.x.x.x （x代表学号最后两位，便学号从01-09的取1-9）。
举例学号为2017107201则AR3的loopback0IP地址为1.1.1.1。
2、在PC1上ping 通4.4.4.4和41.41.41.41。
3、在AR1上配置默认静态路由。

三、实现

在AR1中添加如下：

在AR2中添加如下：

然后启动程序。
开始在AR1,AR2,AR3,AR4中配置静态路由。
