实验为路由IP地址汇总，本实验环境为小凡搭建！！
本人亲做！望大家支持！
先看一下ip地址汇总的方法吧
把这几个网络地址展开为2进制的，然后看相同的网络位，连续而且相同的网络位就是这几个网络地址的汇总地址了，例如：
172.168.4.1/24
172.168.5.1/24
172.168.6.1/24
172.168.7.1/24
这几个地址展开来是：
10101100.10101000.00000100.00000001
10101100.10101000.00000101.00000001
10101100.10101000.00000110.00000001
10101100.10101000.00000111.00000001
他们都有相同的前22位，所以汇总地址就是 172.168.4.0/22
还有，汇总只能汇总到主类的边界，也就是说A类只能汇总到/8，B类只能汇总到/16，C类只能汇总到/24。
只有CIDR才可以突破主类边界。
好了，来看实验过程！！
