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(wǎng)段的網(wǎng)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(wǎng)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實驗最終結果：拓撲圖下各個PC均能相互通信交換機的配置命令：SW 0:Switch
