案例要求：需要不通网段的PC1与PC2、PC3主机分别ping通
准备：三台PC端主机、三台路由器(AR2220)
操作：

1. 配置PC端网络信息
   PC1配置截图：
   
   注意：配置静态路由无需选择DHCP分配，需要自己设置的，这里的网关即下列步骤中的AR1的GE0的串口端ip
   PC2、PC3的配置同理
2. 配置路由器
   打开路由器AR1后配置：
   system-view #进入系统界面
   [Huawei]interface GigabitEthernet 0/0/0 # 进入G端口
   [Huawei-GigabitEthernet0/0/0]ip addr 10.123.1.1 24 # 配置G端口的IP地址和子网掩码
   [Huawei-GigabitEthernet0/0/0]quit # 返回上一界面
   [Huawei]interface GigabitEthernet 0/0/1
   [Huawei-GigabitEthernet0/0/1]ip addr 1.1.1.1 24
   [Huawei-GigabitEthernet0/0/1]quit
   [Huawei]ip route-static 20.123.1.0 24 1.1.1.2 # 配置添加静态路由信息，目标网络，掩码，下一跳
   [Huawei]interface GigabitEthernet 0/0/2 # 进入G端口
   [Huawei-GigabitEthernet0/0/2]ip addr 2.2.2.1 24 # 配置G端口的IP地址和子网掩码
   [Huawei-GigabitEthernet0/0/2]quit
   [Huawei] ip route-static 30.123.1.0 24 2.2.2.2
   查看路由表：
   
   其中static标识的就是咱们设置的静态地址路由
   配置AR2路由器：
   system-view
   [Huawei]interface GigabitEthernet 0/0/0
   [Huawei-GigabitEthernet0/0/0]ip addr 1.1.1.2 24
   [Huawei-GigabitEthernet0/0/0]quit
   [Huawei]interface GigabitEthernet 0/0/1
   [Huawei-GigabitEthernet0/0/1]ip addr 20.123.1.1 24
   [Huawei-GigabitEthernet0/0/1]quit
   [Huawei]ip route-static 10.123.1.0 30 1.1.1.1
   查看AR2路由表：
   
   配置AR3路由器：
   system-view
   [Huawei]interface GigabitEthernet 0/0/0
   [Huawei-GigabitEthernet0/0/0]ip addr 30.123.1.1 24
   [Huawei-GigabitEthernet0/0/0]quit
   [Huawei]interface GigabitEthernet 0/0/1
   [Huawei-GigabitEthernet0/0/1]ip addr 2.2.2.2 24
   [Huawei-GigabitEthernet0/0/1]quit
   [Huawei]ip route-static 10.123.1.0 30 2.2.2.1
   查看AR3路由表：
   
3. 测试路由
