路由器AR3配置
[AR3]interface GigabitEthernet 0/0/0
[AR3-GigabitEthernet0/0/0]ip address 192.168.2.2 24
[AR3]interface GigabitEthernet 0/0/1
[AR3-GigabitEthernet0/0/1]ip address 192.168.3.1 24
配置AR4
[AR4]interface GigabitEthernet 0/0/0
[AR4-GigabitEthernet0/0/0]ip address 192.168.3.2 24
如何查看配置好的IP地址呢？有兩種方式
我們可以進入某個接口通過命令display this 查詢這個接口的IP
[AR2]interface GigabitEthernet 0/0/0
[AR2-GigabitEthernet0/0/0]display this
第二種通過命令：display ip interface brief查看所有接口IP
