华为DHCP中继配置案例 – 六安创世纪网络工程

一，网络拓扑搭建

网络拓扑基于eNSP如下图
- R2作为DHCP服务器，接口ethernet0/0/0 ip:10.1.1.2/24
- R1作为中继路由器，接口Ethernet0/0/0 ip:10.1.1.1/24
- R1GE0/0/1口设置trunck口
- LSW1 GE0/0/1设置为trunck口
- LSW1 ethernet0/0/1设置vlan 10,ethernet0/0/2设置为vlan20,ethnet0/0/3设置为vlan30

二，配置阶段

1，在R2上配置DHCP服务器，具体如下：

开启DHCP服务
#
dhcp enable
#
配置地址池
#
ip pool vlan10
 gateway-list 192.168.10.1
 network 192.168.10.0 mask 255.255.255.0
#
ip pool vlan20
 gateway-list 192.168.20.1
 network 192.168.20.0 mask 255.255.255.0
#
ip pool vlan30
 gateway-list 192.168.30.1
 network 192.168.30.0 mask 255.255.255.0
#
 设置接口地址，启用DHCP全局dhcp select global                                       
#
interface Ethernet0/0/0
 ip address 10.1.1.2 255.255.255.0
 dhcp select global    
# 
配置R2回程路由，如下图：
#
ip route-static 192.168.0.0 255.255.0.0 10.1.1.1
#

2，配置DHCP中继路由器R1

开启DHCP功能
#
dhcp enable
#
配置接口中继，DHCP中继远端server-ip 10.1.1.2
#
interface Vlanif10
 ip address 192.168.10.1 255.255.255.0
 dhcp select relay
 dhcp relay server-ip 10.1.1.2
#
interface Vlanif20                        
 ip address 192.168.20.1 255.255.255.0
 dhcp select relay
 dhcp relay server-ip 10.1.1.2
#
interface Vlanif30
 ip address 192.168.30.1 255.255.255.0
 dhcp select relay
 dhcp relay server-ip 10.1.1.2
#
R1 Ethernet0/0/0接口ip地址配置
#
interface Ethernet0/0/0
 ip address 10.1.1.1 255.255.255.0
#
R1 GigabitEthernet0/0/1 二层trunck口设置
#
interface GigabitEthernet0/0/1
 portswitch
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
#

3，交换机LSW1设置

LSW1二层接口配置如下：
#
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
#

#
interface Ethernet0/0/2
 port link-type access
 port default vlan 20
#
interface Ethernet0/0/3
 port link-type access
 port default vlan 30
#
