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 交换机的配置命令: SW 0: Switch> Switch>en Switch#conf Configuring from terminal, memory, or network [terminal]?
