思科设备参考：DHCP自动获取IP地址实验（思科）

一，实验目的

路由器搭载DHCP，让PC通过DHCP自动获取IP地址

二，不划分vlan--全局地址池

实验拓扑

配置命令

Router

<Huawei>system-view

[Huawei]ip pool mypool

[Huawei-ip-pool-mypool]network 192.168.10.0

[Huawei-ip-pool-mypool]excluded-ip-address 192.168.10.10 192.168.10.254

[Huawei-ip-pool-mypool]lease day 2 hour 0 minute 0

[Huawei-ip-pool-mypool]dns-list 114.114.114.114

[Huawei-ip-pool-mypool]quit

[Huawei]dhcp enable

[Huawei]int g0/0/0

[Huawei-GigabitEthernet0/0/0]ip address 192.168.10.254 24

[Huawei-GigabitEthernet0/0/0]dhcp select global

[Huawei-GigabitEthernet0/0/0]quit

[Huawei]display current-configuration

测试结果

PC1 和 PC2 成功获取到 IP 地址

① 打开PC--->基础配置--->IPv4配置--->DHCP--->应用

② 命令行--->输入指令 ipconfig /renew

三，划分vlan--接口地址池

实验拓扑

配置命令

Switch
