实验题目及要求：
1、分析IP地址分配。
主干IP掩码均为30；
环回IP掩码为28，方便汇总掩码27；
然后预留部分IP地址。
如下图：
2、按如上图片要求连接设备，并标记好IP分配信息，便于命令配置时一目了然。
3、进入各路由器VRP界面开始命令配置，配置IP地址命令如下（含解析）：
R1：
<Huawei>sys //进入第二层
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname r1 //将路由器改名为r1
[r1]int g 0/0/0 //进入接口，按之前信息标注开始配置IP地址

以上操作基本就把该实验完成了，最后验证就需要断开R4的0/0/2口进行测试、然后利用R1来ping
