H3C设备之DHCP中继代理

 

 

使用DHCP中继代理，让DHCP客户端通过代理动态获取地址。

DHCP SERVER: 

[H3C]interface E1/1

          ip address 192.168.1.10 24

[H3C] dhcp enable

           dhcp server forbidden-ip 192.168.2.1 192.168.2.10

           dhcp server ip-pool dhcp1

           network 192.168.2.0 mask 255.255.255.0

           gateway-list 192.168.2.1 

           dns-list 22.22.22.2

           ip route-static 192.168.2.0 255.255.255.0 192.168.1.1

DHCP RELAY:  

 [H3C]interface E1/1

           ipaddress 192.168.1.1 24

           interface E1/0

           ip address 192.168.2.1 24

 [H3C]dhcp enable

          dhcp relay server-group 1 ip 192.168.1.10     配置DHCP地址组，并且指定DHCP server 地址。

           interface E1/0

           dhcp select relay          使接口工作在中继模式下

           dhcp relay server-select 1    将接口与DHCP组关联

 [H3C]ip route-static 192.168.1.0 255.255.255.0 192.168.1.10

此时DHCP CLINET成功通过代理获取到了动态地址信息：
