华为交换机配置dhcp中继

华为交换机配置dhcp中继

两个步骤：
一、配置核心交换机（图中LSW1）
(1).接口配置：

   int gig0/0/1
   port link-type access
   port default vlan 10
   
   int gig0/0/2
   port link-type access
   port default vlan 20

   int gig0/0/3
   port link-type access
   port default vlan 50

(2).dhcp 中继配置：

	[Sw1] dhcp enable                 //开启全局
	[Sw1] dhcp server group yukong    //创建dhcp服务器组 yukong
	[Sw1-dhcp-server-group-yukong] dhcp-server 10.3.50.50  //绑定服务器地址
	
	[Sw1]int vlan 10
	       ip add 10.0.0.1 24
	       dhcp select relay    //dhcp服务器选择 转发模式
           dhcp relay server-select yukong  //选择转发 dhcp的服务器
	[Sw1]int vlan 20
	       ip add 20.0.0.1 24
	       dhcp select relay
           dhcp relay server-ip 10.3.50.50            //server-select 和 server-ip  都可以

二、配置dhcp服务器（图中AR1）

(1).配置dhcp地址池
	ip pool vlan10
       gateway-list 10.0.0.1 
       network 10.0.0.0 mask 255.255.255.0 
       dns-list 114.114.114.114
    ip pool vlan20
       gateway-list 20.0.0.1 
       network 20.0.0.0 mask 255.255.255.0 
       dns-list 114.114.114.114
   
(2).开启dhcp功能并调用
    [R1]dhcp enable
    [R1]int gig 0/0/0
          ip add 10.3.50.50 24
          dhcp select global
          
(3).配置路由
	ip router-static 10.0.0.0 24 10.3.50.1
	ip router-static 20.0.0.0 24 10.3.50.1
