本文将介绍如何在华为路由器上配置DHCP服务，实现自动向局域网内的主机分配IP地址的目的。拓扑如下：

DHCP有两种配置方式，具体配置如下：

1.按接口地址池的方式配置：

[Huawei]interface g0/0/0

[Huawei-GigabitEthernet0/0/0]ip add 192.168.1.1 255.255.255.0

[Huawei-GigabitEthernet0/0/0]undo shutdown

[Huawei-GigabitEthernet0/0/0]dhcp select interface

[Huawei-GigabitEthernet0/0/0]dhcp server dns-list 192.168.20.50

[Huawei-GigabitEthernet0/0/0]dhcp server excluded-ip-address 192.168.1.1

[Huawei-GigabitEthernet0/0/0]dhcp server lease day 1

2.按全局地址池的方式配置：

[Huawei]dhcp enable

[Huawei]ip pool qgtest

[Huawei-ip-pool- qgtest]network 192.168.1.0 mask 24

[Huawei-ip-pool- qgtest]gateway-list 192.168.1.1

[Huawei-ip-pool- qgtest]lease day 1

[Huawei]interface g0/0/0

[Huawei-GigabitEthernet0/0/0]dhcp select global
