本文通过拓扑图和设备配置，详细介绍了如何在华为设备上设置DHCP中继，包括PC设置为DHCP获取IP，配置VLAN，AR1作为DHCP服务器，创建地址池，设定静态路由，以及在交换机SW1上配置DHCP中继，最后验证了PC1到PC4获取IP的效果。

拓扑图

在这里插入图片描述

设备配置

PC设置选择DHCP获取IP
将PC划分进vlan
AR1充当DHCP服务器
在AR1配置两个地址池
添加两条到客户机的静态路由
地址池下发

[R1-GigabitEthernet0/0/0]dhcp enable      
[R1]ip pool dhcp1
[R1-ip-pool-dhcp1]network 192.168.10.0 mask 255.255.255.0

[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]dhcp select global 
[R1-GigabitEthernet0/0/0]quit

在SW1上，设置DHCP中继

[L3-SW1]int vlan 10
[L3-SW1-Vlanif10]dhcp select relay
[L3-SW1-Vlanif10]dhcp relay server-ip 10.1.1.1
[L3-SW1-Vlanif10]int vlan 20
[L3-SW1-Vlanif20]dhcp select relay 	
[L3-SW1-Vlanif20]dhcp relay server-ip 10.1.1.1
[L3-SW1-Vlanif20]quit

在PC上查看结果
