要在三层交换机启用ip routing,把不同的终端放到不通的vlan里面,把vlan业务做到三层交换机上,我这边有个案列,你可以看看
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
