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 4.1 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 4.2 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 6.1 查看PC2、PC3的地址获取情况 [PC2]display ip interface brief Interface IP Address/Mask Physical Protocol
