Trunk必看版，最基礎，最簡單的實驗

小白必看：超簡單Trunk小實驗,一看就懂

一.實驗環境

實驗環境：GNS3，路由器c2691

二.實驗拓撲圖<img src="https://cache.yisu.com/upload/information/20200309/33/53641.jpg" alt="mark" style="zoom:75%;" />

三.實驗步驟

首先進行vlan與接口的配置。先設置好vlan如圖。<img src="https://cache.yisu.com/upload/information/20200309/33/53642.jpg" alt="mark" style="zoom:75%;" />

然后把sw1的接口分給對應的vlan<img src="https://cache.yisu.com/upload/information/20200309/33/53644.jpg" alt="mark" style="zoom:75%;" />

接著我們對sw2進行同樣的操作。如圖。<img src="https://cache.yisu.com/upload/information/20200309/33/53645.jpg" alt="mark" style="zoom:75%;" />

接著我們要對sw1的f1/2接口設置trunk，如圖<img src="https://cache.yisu.com/upload/information/20200309/33/53646.jpg" alt="mark" style="zoom:75%;" />

接下來對sw2的f1/2接口進行同樣的設置，如圖<img src="https://cache.yisu.com/upload/information/20200309/33/53647.jpg" alt="mark" style="zoom:75%;" />

最后我們再對pc機設置ip地址就行了。如下圖依次是pc1到pc4的設置。<img src="https://cache.yisu.com/upload/information/20200309/33/53648.jpg" alt="mark" style="zoom:75%;" />

至此實驗結束，實驗結果如何大家可以自行互ping試試，用wireshark抓包看看實驗結果。over！
