DHCP三种配置方式

1.采用interface模式配置：
拓扑图：

AR1配置：
1.配置网关
[AR1]interface g0/0/0
[AR1-GigabitEthernet0/0/0]ip address 192.16.1.1 24
2.配置dhcp:
[AR1]dhcp enable
[AR1]int g0/0/0
[AR1-GigabitEthernet0/0/0]dhcp select interface
[AR1-GigabitEthernet0/0/0]dhcp server dns-list 192.168.1.2
[AR1-GigabitEthernet0/0/0]dhcp server excluded-ip-address 192.168.1.2

PC配置：
只需要在pc端开启dhcp获取地址即可

2.采用global模式
拓扑图：

AR3配置：
1.配置网关：
sys
[Huawei]interface g0/0/0
[Huawei-GigabitEthernet0/0/0]ip add 192.168.1.1 24
2.配置dhcp:
[Huawei]dhcp enable
[Huawei]ip pool 1
[Huawei-ip-pool-1]network 192.168.1.0 mask 24
[Huawei-ip-pool-1]gateway-list 192.168.1.1
[Huawei-ip-pool-1]dns-list 192.168.1.2
[Huawei-ip-pool-1]excluded-ip-address 192.168.1.2
[Huawei-ip-pool-1]quit
[Huawei]int g0/0/0
[Huawei-GigabitEthernet0/0/0]dhcp select global
2.pc配置：
同上

3.relay模式
拓扑图：

AR3配置：
1.配置接口：
[AR3]interface g0/0/0
[AR3-GigabitEthernet0/0/0]ip add 192.168.23.3 24
2.dhcp配置：
[AR3]dhcp enable
[AR3]ip pool 1
[AR3-ip-pool-1]network 192.168.12.0 mask 24
[AR3-ip-pool-1]gateway-list 192.168.12.2
[AR3-ip-pool-1]quit
[AR3] int g0/0/0
[AR3-GigabitEthernet0/0/0] dhcp select global
[AR3]ip route-static 192.168.12.0 24 192.168.23.2

AR2配置
1.配置接口：
[AR2}interface g0/0/0
[AR2-GigabitEthernet0/0/0]ip add 192.168.12.2 24
[AR2-GigabitEthernet0/0/0]quit
[AR2]interface g0/0/1
[AR2-GigabitEthernet0/0/1]ip add 192.168.23.2 24
2.dhcp配置：
[AR2] dhcp enable
[AR2]int g0/0/0
[AR2-GigabitEthernet0/0/0]dhcp select relay
[AR2-GigabitEthernet0/0/0]dhcp relay server-ip 192.168.23.3

AR1配置
[AR1] dhcp enable
[AR1] int g0/0/0
[AR1-GigabitEthernet0/0/0] ip address dhcp-alloc
