简单配置DHCP中继

大家好，欢迎来到IT知识分享网。

今天分享DHCP中继服务器配置，依华为模拟器实验，AR路由器模拟DHCP中继服务器，也可通过用一朵小白云，虚拟服务器模拟DHCP中继服务器

1、拓扑图

2、配置DHCP中继服务器

sysname DHCP_server

#

dhcp enable

#

ip pool vlan10

gateway-list 172.16.10.254

network 172.16.10.0 mask 255.255.255.0

excluded-ip-address 172.16.10.220 172.16.10.253

dns-list 223.5.5.5 223.6.6.6

#

ip pool vlan30

gateway-list 10.10.30.254

network 10.10.30.0 mask 255.255.255.0

excluded-ip-address 10.10.30.201 10.10.30.253

lease day 2 hour 0 minute 0

dns-list 8.8.8.8 114.114.114.114

#

interface G0/0/1

ip address 192.168.100.2 30

dhcp select global #配置DHCP全局模式

#

ip route-static 0.0.0.0 0.0.0.0 192.168.100.1

3、配置核心交换机

sysname HX_LSW1

#

vlan batch 10 30 100

#

dhcp enable

#

interface Vlanif10

ip address 172.16.10.254 255.255.255.0

dhcp select relay

dhcp relay server-ip 192.168.100.2

#

interface Vlanif30

ip address 10.10.30.254 255.255.255.0

dhcp select relay

dhcp relay server-ip 192.168.100.2

#

interface Vlanif100 #配置接口IP，连接DHCP中继服务器接口

ip address 192.168.100.1 30

#

interface G0/0/2

port link-type trunk

undo port trunk allow-pass vlan 1

port trunk allow-pass vlan 10 30

#

int G0/0/24 #配置接口IP，连接DHCP中继服务器接口

port link-type access

port default vlan 100

4、配置接入交换，二层交换机

sysname JR_SW2

#

vlan batch 10 30

#

interface Ethernet0/0/1

port link-type access

port default vlan 10

#

interface Ethernet0/0/

port link-type access

port default vlan 30

#

interface GigabitEthernet0/0/1

port link-type trunk

undo port trunk allow-pass vlan 1

port trunk allow-pass vlan 10 30

5、测试

dis ip pool name vlan10 used #查看分配的IP地址
