实验要求:

优化及要求：

1，AS1存在两个环回，，一个地址为192.168.1.0/24该地址不能在任何协议中宣告,

AS3中存在两个环回，一个地址为192.168.2./24该地址不能在任何协议中宣告，最终要求这两个环回可以互相通讯

2，整个AS2的Ip地址为172.16.0.0/16，请合理划分

3，AS间的骨干链路IP地址随意定制

4，使用BGP协议让整个网络所有设备的环回可以互相访问,减少路由条自数量，避免环路出现

拓扑设计：

步骤一：地址划分

总地址网段：172.16.0.0 /16

骨干链路：172.16.0.0 /24划分至30位

        172.16.0.0  30

        172.16.0.4  30

        172.16.0.8  30

        ......

建邻的环回地址：172.16.1.0 /24下的主机地址

        172.16.1.2/32

        172.16.1.3/32

        172.16.1.4/32 

         ........

用户网段：172.16.2.0 /24   172.16.3.0 /24   172.16.4.0 24 ......

步骤二：拓扑建立，IP地址配置
