网络实验拓扑图 AR1配置: 进入系统模式，可以进行一些简单的配置 system-view 进入接口模式配置接口的IP地址 [Huawei]interface GigabitEthernet 0/0/2 [Huawei-GigabitEthernet0/0/2]ip address 172.16.0.1 20 [Huawei-GigabitEthernet0/0/2]quit [Huawei]interface GigabitEthernet 0/0/1 [Huawei-GigabitEthernet0/0/1]ip address 172.16.32.1 20 [Huawei-GigabitEthernet0/0/1]quit [Huawei]interface GigabitEthernet 0/0/0 [Huawei-GigabitEthernet0/0/0]ip address 172.16.48.1 20 [Huawei-GigabitEthernet0/0/0]quit [Huawei]interface GigabitEthernet 1/0/0 [Huawei-GigabitEthernet1/0/0]ip address 172.16.16.1 20 [Huawei-GigabitEthernet1/0/0]quit
创建dhcp地址池并启用DHCP使dhcp服务器下的pc自动获取ip地址 应AR1下需两个网段，所以需要创建两个dhcp地址池 启用dhcp [Huawei]dhcp enable 创建pool [Huawei]ip pool 1 定义网络范围 [Huawei-ip-pool-1]network 172.16.0.0 mask 20 [Huawei-ip-pool-1]gateway-list 172.16.0.1 dns解析 [Huawei-ip-pool-1]dns-list 114.114.114.114 [Huawei-ip-pool-1]quit [Huawei]ip pool 2 [Huawei-ip-pool-2]network 172.16.16.0 mask 20 [[Huawei-ip-pool-2]gateway-list 172.16.16.1 [Huawei-ip-pool-2]dns-list 114.114.114.114 [Huawei-ip-pool-2]quit [Huawei]interface GigabitEthernet 0/0/2 [Huawei-GigabitEthernet0/0/2]dhcp select global [Huawei-GigabitEthernet0/0/2]quit [Huawei]interface GigabitEthernet 1/0/0 [Huawei-GigabitEthernet1/0/0]dhcp select global [Huawei-GigabitEthernet1/0/0]quit
