配置设备作为DHCP中继示例（中继与服务器处于同一网络）
组网需求
如图1所示，某企业部署一台DHCP服务器（SwitchB），希望为企业内终端动态分配IP地址，终端与DHCP服务器部署在不同网段。
图1 配置设备作为DHCP中继组网图
配置思路
配置设备作为DHCP中继的配置思路如下：
在SwitchA上配置DHCP中继，设备作为DHCP中继转发终端与DHCP服务器间的DHCP报文，从而实现DHCP服务器为终端分配IP地址。
DHCP服务器（SwitchB）以S2750&S5700&S6720系列交换机为例。
操作步骤
在SwitchA上配置DHCP中继。
# 配置接口加入VLAN。
<HUAWEI> system-view
[HUAWEI] sysname SwitchA
[SwitchA] vlan batch 100 200
[SwitchA] interface gigabitethernet 0/0/2
[SwitchA-GigabitEthernet0/0/2] port link-type hybrid
[SwitchA-GigabitEthernet0/0/2] port hybrid pvid vlan 100
[SwitchA-GigabitEthernet0/0/2] port hybrid untagged vlan 100
[SwitchA-GigabitEthernet0/0/2] quit
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] port link-type hybrid
[SwitchA-GigabitEthernet0/0/1] port hybrid pvid vlan 200
[SwitchA-GigabitEthernet0/0/1] port hybrid untagged vlan 200
[SwitchA-GigabitEthernet0/0/1] quit
[SwitchA] interface vlanif 200
[SwitchA-Vlanif200] ip address 10.10.20.1 24
[SwitchA-Vlanif200] quit
# 在接口下使能DHCP中继功能。
[SwitchA] dhcp enable
[SwitchA] interface vlanif 100
[SwitchA-Vlanif100] ip address 10.20.20.1 24
[SwitchA-Vlanif100] dhcp select relay
[SwitchA-Vlanif100] dhcp relay server-ip 10.10.20.2
[SwitchA-Vlanif100] quit
在SwitchA上配置缺省路由。
[SwitchA] ip route-static 0.0.0.0 0.0.0.0 10.10.20.2
在SwitchB上配置基于全局地址池的DHCP服务器功能。
# 使能DHCP服务。
<HUAWEI> system-view
[HUAWEI] sysname SwitchB
[SwitchB] dhcp enable
# 配置接口VLANIF200工作在全局地址池模式。
[SwitchB] vlan 200
[SwitchB-vlan200] quit
[SwitchB] interface gigabitethernet 0/0/1
[SwitchB-GigabitEthernet0/0/1] port link-type hybrid
[SwitchB-GigabitEthernet0/0/1] port hybrid pvid vlan 200
[SwitchB-GigabitEthernet0/0/1] port hybrid untagged vlan 200
[SwitchB-GigabitEthernet0/0/1] quit
[SwitchB] interface vlanif 200
[SwitchB-Vlanif200] ip address 10.10.20.2 24
[SwitchB-Vlanif200] dhcp select global
[SwitchB-Vlanif200] quit
# 创建地址池并配置相关属性。
[SwitchB] ip pool pool1
[SwitchB-ip-pool-pool1] network 10.20.20.0 mask 24
[SwitchB-ip-pool-pool1] gateway-list 10.20.20.1
[SwitchB-ip-pool-pool1] option121 ip-address 10.10.20.0 24 10.20.20.1
[SwitchB-ip-pool-pool1] quit
在SwitchB上配置缺省路由。
[SwitchB] ip route-static 0.0.0.0 0.0.0.0 10.10.20.1
验证配置结果。
# 在SwitchA上执行命令display dhcp relay interface vlanif 100命令用来查看DHCP中继的配置信息。
[SwitchA] display dhcp relay interface vlanif 100
DHCP relay agent running information of interface Vlanif100 :
Server IP address [00] : 10.10.20.2
Gateway address in use : 10.20.20.1
# 在SwitchB上使用display ip pool name pool1命令用来查看IP地址池的分配情况，“Used”字段表示已经分配出去的IP地址数量。
[SwitchB] display ip pool name pool1
