1、欢迎共阅三层交换机与路由器的配置实例（图解）目的：学会使用三层交换与路由器让处于不同网段的网络相互通信实验步骤：一：二层交换机的配置：在三个二层交换机上分别划出两VLAN ，并将二层交换机上与三层交换或路由器上的接线设置为 trunk 接口二：三层交换机的配置：1：首先在三层交换上划出两个VLAN ，并进入 VLAN 为其配置 IP，此 IP 将作为与他相连PC的网关。2：将与二层交换机相连的线同样设置为trunk 接线，并将三层交换与路由器连接的线设置为路由接口（ no switchsport）3：将路由器和下面的交换机进行单臂路由的配置实验最终结果：拓扑图下各个PC均能相互通信交换机的配置
