DHCP 中继 配置方法

配置 三层交换机作为中继完成不同VLAN的ip地址分配

实验topo图如图所示

DHCP server配置如下

sys
sys server
dhcp enable
int g0/0/0
ip add 12.0.0.253 24
ip pool 10
network 192.168.10.0 mask 24
gateway-list 192.168.10.254
ip pool 20
network 192.168.20.0 mask 24
gateway-list 192.168.20.254
int g0/0/0
dhcp select global
q
ip route-s 192.168.0.0 16 12.0.0.254

DHCP 中继配置如下

sys
sys replay
dhcp enable

vlan batch 10 20
int vlanif 10
ip add 192.168.10.254 24
dhcp select relay 
dhcp relay server-ip 12.0.0.253
int vlanif 20
ip add 192.168.20.254 24
dhcp select relay 
dhcp relay server-ip 12.0.0.253

vlan 200
int g0/0/3
p l t
p t a v all
int g0/0/1
p l a
p d v 200
int vlanif 200
ip add 12.0.0.254 24

交换机配置如下

sys
vlan batch 10 20
int e0/0/1
p l t
p t a v all
int e0/0/2
p l a
p d v 10
int e0/0/3
p l a
p d v 20
