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:
