實操：華爲單臂路由和dhcp服務配置實驗，簡單有效

華爲設備單臂路由實驗

實驗對象：一臺路由器、一臺交換機、兩臺PC機
實驗環境：eNSP
實驗原理： interface eth-trunk 1.10
dot1q termination vid 10（該接口屬於vlan10）
ip add 192.168.10.1 24
arp broadcast enable（開啓arp廣播）

注意：在生產環境中，要先查看版本，保存信息，然後根據當前環境確定是否需要升級系統，這是個好習慣

PC配置

華爲設備DHCP服務配置

需要的環境安裝在之前的博客提及，需要了解的可以去看
實驗對象：兩臺路由器，一臺交換機，五臺PC機
實驗環境：eNSP
實驗原理：華爲設備的DHCP基本原理
第一步：客戶端通過廣播發送DHCP Discover 報文尋服務器端
第二步：服務器端通過單播發送DHCP Offer 報文向客戶端提供IP地址等網絡信息
第三步：客戶端通過廣播DHCP Request 報文告知服務器端本地選擇使用哪個IP地址
第四步：服務器通過DHCP Ack報文告知客戶端IP地址是合法可用的
其中是兩個廣播，兩個單播，與linux的dhcp原理不同
