【华为】DHCP服务配置

A、 拓扑图：

B、 配置命令与步骤

一、华为DHCP-interface地址池配置：

[R1]dhcp enable

[R1]int e0/0/1

[R1-Ethernet0/0/1]ip add 192.168.11.1 24

[R1-Ethernet0/0/1]dhcp select interface

[R1-Ethernet0/0/1]dhcp server dns-list 2.2.2.2

[R1-Ethernet0/0/1]dhcp server excluded-ip-address 192.168.11.168

[R1-Ethernet0/0/1]dhcp server lease day 1

二、华为DHCP全局地址池配置（本地）：

[R1]ip pool client2

[R1-ip-pool-client2]network 192.168.12.0 mask 24

[R1-ip-pool-client2]dns-list 2.2.2.2

[R1-ip-pool-client2]gateway-list 192.168.12.1

[R1-ip-pool-client2]excluded-ip-address 192.168.12.88

[R1-ip-pool-client2]lease day 1

[R1]int g0/0/2

[R1-GigabitEthernet0/0/2]ip add 192.168.12.1 24

[R1-GigabitEthernet0/0/2]dhcp select global

三、华为DHCP-relay配置：

[R2]dhcp enable

[R2-Ethernet0/0/0]dhcp select relay

[R2-Ethernet0/0/0]dhcp relay server-ip 12.1.1.1

[R1]ip pool client3

[R1-ip-pool-client2]network 172.16.23.0 mask 24

[R1-ip-pool-client2]dns-list 2.2.2.2

[R1-ip-pool-client2]gateway-list 172.16.23.2

[R1-ip-pool-client2]excluded-ip-address 172.16.23.88

[R1-ip-pool-client2]lease day 1

[R1-Ethernet0/0/0]dhcp select global

[R1]ip route-static 172.16.23.0 24 e0/0/0 12.1.1.2
