1、dhcp作為公司匯聚交換機，在上面配置dhcp全域性位址池，然後接入交換機根據不同vlan會獲取到不同網段ip位址。

2、網路拓撲

1、客戶端

1）建立dhcp伺服器組，並為dhcp伺服器組新增dhcp伺服器對應網段的閘道器ip

system-view 


[huawei]sysname client


[client]dhcp server group dhcp1


[client-dhcp-server-group-dhcp1]dhcp-server 192.168.1.1


[client-dhcp-server-group-dhcp1]q


[client]dhcp server group dhcp2


[client-dhcp-server-group-dhcp2]dhcp-server 192.168.2.1


[client-dhcp-server-group-dhcp2]q
2）建立vlan

[client]vlan batch 10 20
3）使能全域性dhcp功能

[client]dhcp enable
4）開啟vlanif中繼功能並配置介面ip，指定dhcp伺服器。

[client]inte***ce  vlanif 10


[client-vlanif10]dhcp select relay 


[client-vlanif10]ip address 192.168.1.2 24


[client-vlanif10]dhcp relay server-select dhcp1


[client-vlanif10]q


[client]inte***ce vlanif 20


[client-vlanif20]dhcp select relay 


[client-vlanif20]ip address 192.168.2.2 24


[client-vlanif20]dhcp relay server-select dhcp2


[client-vlanif20]q
5）配置介面

[client]inte***ce  gigabitethernet  0/0/1


[client-gigabitethernet0/0/1]port link-type trunk 


[client-gigabitethernet0/0/1]port trunk allow-pass vlan all 


[client-gigabitethernet0/0/1]q


[client]inte***ce gigabitethernet 0/0/2


[client-gigabitethernet0/0/2]port link-type access 


[client-gigabitethernet0/0/2]port default vlan 10


[client-gigabitethernet0/0/2]q


[client]inte***ce gigabitethernet 0/0/3


[client-gigabitethernet0/0/3]port link-type access 


[client-gigabitethernet0/0/3]port default vlan 20


[client-gigabitethernet0/0/3]q
2、dhcp伺服器

1）使能dhcp

system-view 


[huawei]sysname dhcp 


[dhcp]dhcp enable
2）建立vlan，配置ip位址，並讓vlan介面下的客戶端從全域性位址池中獲取ip

[dhcp]vlan batch 10 20


[dhcp]inte***ce vlanif 10


[dhcp-vlanif10]ip address 192.168.1.1 24


[dhcp-vlanif10]dhcp select global 


[dhcp-vlanif10]q


[dhcp]inte***ce vlanif 20


[dhcp-vlanif20]ip address 192.168.2.1 24


[dhcp-vlanif20]dhcp select global 


[dhcp-vlanif20]q
3）配置全域性位址池

[dhcp]ip pool 1


[dhcp-ip-pool-1]network 192.168.1.0 mask 24


[dhcp-ip-pool-1]gateway-list 192.168.1.1


[dhcp-ip-pool-1]lease day 1


[dhcp-ip-pool-1]q


[dhcp]ip pool 2


[dhcp-ip-pool-2]network 192.168.2.0 mask 24


[dhcp-ip-pool-2]gateway-list 192.168.2.1 


[dhcp-ip-pool-2]lease day 1


[dhcp-ip-pool-2]q
4）配置介面

[dhcp]inte***ce  gigabitethernet  0/0/1


[dhcp-gigabitethernet0/0/1]port link-type trunk 


[dhcp-gigabitethernet0/0/1]port trunk allow-pass vlan all 


[dhcp-gigabitethernet0/0/1]q
3、驗證

1）pc設定自動獲取ip

2）ping測試
