1、三層交換機與路由器的配置 實例(圖解)目的：學會使用三層交換與路由器讓處于不同網段的網絡相互通信實驗步驟：一：二層交換機的配置：在三個二層交換機上分別劃出兩 VLAN，并將二層交換機上與三層交換或路由器上的接線設置為 trunk 接口二：三層交換機的配置：1：首先在三層交換上劃出兩個 VLAN，并進入 VLAN為其配置 IP ，此 IP 將作為與他相連 PC的網 關。2：將與二層交換機相連的線同樣設置為 trunk 接線，并將三層交換與路由器連接的線設置為路 由接口( no switchsport )3：將路由器和下面的交換機進行單臂路由的配置交換機的配置命令：SW 0:Switch>S
