交换机启用中继功能，路由器配置两个vlan的地址池

pool10给vlan10分配ip，pool20给vlan20分配ip

# pool10

# 地址池

192.168.10.0/24

# dns

8.8.8.8

# 网关

192.168.10.1

------------------------------------------

# pool20

# 地址池

192.168.20.0/24

# dns

8.8.8.8

# 网关

192.168.10.1

交换机配置命令

# 创建vlan

vlan batch 10 20 100

# 全局启用DHCP

dhcp enable

# 配置接口

int g0/0/1

port link-type access

port default vlan 100

int g0/0/2

port link-type access

port default vlan 10

int g0/0/3

port link-type access

port default vlan 20

# 配置vlan口ip

int vlanif 100

ip add 192.168.100.1 24

int vlanif 10

ip add 192.168.10.1 24

int vlanif 20

ip add 192.168.20.1 24

# vlan口dhcp配置

int vlanif 10

dhcp select relay

dhcp relay server-ip 192.168.100.2

int vlanif 20

dhcp select relay

dhcp relay server-ip 192.168.100.2
