如何配置DHCP中继服务

谁践踏了优雅 2022-01-17 02:15 413阅读 0赞

**通过本实验掌握如何给不同网段配置** **DHCP** **，掌握** **DHCP** **中继配置，了解ip help-address 作用,了解Cisco 路由器的DHCP的配置。也许你会配置DHCP，可是可能遇到的情况是很顺利，有时你的DHCP服务器，和你DHCP 客户端，并不是在同一个网段，而是需要DHCP 给不同的网段主机分配地址。**

**实验过程：**

**第一步：**  **对路由器** **R1** **进行预配置**

**第五步：在** **PC1** **和** **PC2** **上查看获得** **IP** **地址信息**

**开始** **-** **运行** **-cmd-ipconfig /all**

**如图：**  **PC2**

**如图：** **PC1**
