华为dhcp relay配置

dhcp relay

说明 AR4充当dhcp server ，实现AR4给vlan10和vlan 20内的设备分配ip地址

LSW6配置 

[Huawei]int gi0/0/1

[Huawei-GigabitEthernet0/0/1]port trunk allow-pass  vlan  10 20

[Huawei-GigabitEthernet0/0/1]qu

[Huawei]port-group group-member  gi0/0/2  gi0/0/3

[Huawei-port-group]port link-t ac

[Huawei-port-group]port default  vlan 10

LSW7配置 

[Huawei]int gi0/0/1

[Huawei-GigabitEthernet0/0/1]port trunk vlan

[Huawei-GigabitEthernet0/0/1]port trunk a

[Huawei-GigabitEthernet0/0/1]port trunk allow-pass  vlan 10 20

[Huawei-GigabitEthernet0/0/1]qu

[Huawei]port-g group-member  gi0/0/2  gi0/0/3

[Huawei-port-group]port link-t ac

[Huawei-port-group]port default  vlan  20

LSW8配置 

[Huawei]vlan batch 10 20 1111

[Huawei]int gi0/0/3

[Huawei-GigabitEthernet0/0/3]port link-t t

[Huawei-GigabitEthernet0/0/3]port trunk allow-pass  vlan 10 20

[Huawei-GigabitEthernet0/0/3]int gi0/0/2

[Huawei-GigabitEthernet0/0/2]port link-t tr

[Huawei-GigabitEthernet0/0/2]port trunk  allow-pass  vlan 10 20

[Huawei-GigabitEthernet0/0/2]int gi0/0/1

[Huawei-GigabitEthernet0/0/1]port link-t ac

[Huawei-GigabitEthernet0/0/1]port default  vlan 1111

vlan配置ip地址 

[Huawei-Vlanif1111]ip add 192.168.254.1 25

[Huawei-GigabitEthernet0/0/1]int vlan 20

[Huawei-Vlanif20]ip add 192.168.20.1 25

[Huawei-Vlanif20]int vlan 10

[Huawei-Vlanif10]ip add 192.168.10.1 25

dhcp相关

dhcp enable

[Huawei]int vlan 20

[Huawei-Vlanif20]dhcp select relay

[Huawei-Vlanif20]dhcp relay  server-ip  192.168.254.2

[Huawei-Vlanif20]int vlan 10

[Huawei-Vlanif10]dhcp select relay

[Huawei-Vlanif10]dhcp relay  server-ip  192.168.254.2

测试pc网关是否通？

测试通

测试通之后开始配置AR4（dhcp server）

dhcp enable

ip pool vlan_20

network 192.168.20.1 mask  25

gateway-list 192.168.20.1

dns-list 192.168.20.1 192.168.2.1

ip pool vlan_10

network 192.168.10.1 mask  25

gateway-list 192.168.10.1

dns-list 192.168.10.1 192.168.2.1

int gi0/0/0

dhcp select global

ip add 192.168.254.2 25

ip route-static 0.0.0.0 0 192.168.254.1

pc选择dhcp方式得到ip

获得ip地址

实验完成！不懂留言我~
