+1. 设置所有PC的IP地址、子网掩码、网关
+
+2. AR1路由配置
+
+   ```
+   // 基础设置
+   <Huawei>u t m
+   [Huawei]sysname AR1
+   
+   // 配置端口
+   [AR1]int g 0/0/0
+   [AR1-GigabitEthernet0/0/0]ip a 192.168.30.1 24
+   [AR1]int g 0/0/1
+   [AR1-GigabitEthernet0/0/1]ip a 192.168.10.254 24
+   [AR1]int g 0/0/2
+   [AR1-GigabitEthernet0/0/2]ip a 192.168.20.254 24
+   
+   // 配置aaa认证
+   [AR1]aaa
+   [AR1-aaa]local-user ntd2407 password cipher hcip
+   [AR1-aaa]local-user ntd2407 service-type telnet
+   [AR1-aaa]local-user ntd2407 privilege level 15

+
+4. AR3路由配置
+
+   ```
+   // 基础设置
+   <Huawei>u t m
+   [Huawei]sysname AR3
+   
+   // 配置端口
+   [AR3]int g 0/0/0
+   [AR3-GigabitEthernet0/0/0]ip a 192.168.10.2 24
+   
+   // 配置aaa认证
