华为设备单臂路由实验

实验对象：一台路由器、一台交换机、两台PC机
实验环境：eNSP
实验原理： interface eth-trunk 1.10
dot1q termination vid 10（该接口属于vlan10）
ip add 192.168.10.1 24
arp broadcast enable（开启arp广播）

注意：在生产环境中，要先查看版本，保存信息，然后根据当前环境确定是否需要升级系统，这是个好习惯

PC配置

华为设备DHCP服务配置

需要的环境安装在之前的博客提及，需要了解的可以去看
实验对象：两台路由器，一台交换机，五台PC机
实验环境：eNSP
实验原理：华为设备的DHCP基本原理
第一步：客户端通过广播发送DHCP Discover 报文寻服务器端
第二步：服务器端通过单播发送DHCP Offer 报文向客户端提供IP地址等网络信息
第三步：客户端通过广播DHCP Request 报文告知服务器端本地选择使用哪个IP地址
第四步：服务器通过DHCP Ack报文告知客户端IP地址是合法可用的
其中是两个广播，两个单播，与linux的dhcp原理不同
实验拓扑：
