一、实验拓扑

二、实验需求

 PC2通过全局地址池动态获取地址，PC3通过接口地址池获取地址

三、实验配置

1、设备命名

[Huawei]sysname DHCP Server
[Huawei]sysname PC2
[Huawei]sysname PC3

2、IP地址配置

[DHCP Server]interface GigabitEthernet 0/0/0
[DHCP Server-GigabitEthernet0/0/0]ip address 10.1.1.1 24
[DHCP Server]interface GigabitEthernet 0/0/2
[DHCP Server-GigabitEthernet0/0/2]ip address 20.1.1.1 24

3、开启DHCP功能

[DHCP Server]dhcp enable
[PC2]dhcp enable
[PC3]dhcp enable

4、配置地址池
配置全局地址池

[DHCP Server]ip pool 1
[DHCP Server-ip-pool-1]network 10.1.1.0 mask 24
[DHCP Server-ip-pool-1]dns-list 10.1.1.1
[DHCP Server-ip-pool-1]gateway-list 10.1.1.1
[DHCP Server-ip-pool-1]lease day 2
[DHCP Server-ip-pool-1]static-bind ip-address 10.1.1.2 mac-address 00e0-fc68-29dd
[DHCP Server]interface GigabitEthernet 0/0/0
[DHCP Server-GigabitEthernet0/0/0]dhcp select global

配置接口地址池

[DHCP Server]interface GigabitEthernet 0/0/2
[DHCP Server-GigabitEthernet0/0/2]dhcp select interface
[DHCP Server-GigabitEthernet0/0/2]dhcp server dns-list 20.1.1.1

5、配置DHCP客户端

[PC2-GigabitEthernet0/0/0]ip address dhcp-alloc
[PC3-GigabitEthernet0/0/2]ip address dhcp-alloc

6、查看配置结果
查看PC2、PC3的地址获取情况

[PC2]display ip interface brief 
Interface                         IP Address/Mask      Physical   Protocol  
GigabitEthernet0/0/0              10.1.1.2/24          up         up 
[PC3]display ip interface brief 
Interface                         IP Address/Mask      Physical   Protocol       
GigabitEthernet0/0/2              20.1.1.254/24        up         up 

查看DHCP Server地址分配情况

[DHCP Server]display ip pool name 1  
    Pool-name      : 1
    Pool-No        : 1
    Lease          : 2 Days 0 Hours 0 Minutes
    Domain-name    : -
    DNS-server0    : 10.1.1.1        
    NBNS-server0   : -               
    Netbios-type   : -               
    Position       : Local           Status           : Unlocked
    Gateway-0      : 10.1.1.1        
    Mask           : 255.255.255.0
    VPN instance   : --
    Start           End     Total  Used  Idle(Expired)  Conflict  Disable
    10.1.1.1      10.1.1.254   253     1        252(0)         0        0

查看PC2、PC3DNS地址获取情况

[PC2]display dns server
Type:
D:Dynamic     S:Static
No.  Type    IP Address
1     D      1.1.1.10
[PC3]display dns se 
[PC3]display dns server 
Type:
D:Dynamic     S:Static
No.  Type    IP Address
1        D      1.1.1.20

查看是否获取默认路由
