1、利用三层交换机实现不同 VLAN 之间的互访交换机 switch0 和 switch1 创建 4 个 vlan,vlan 10,vlan 20,vlan30,vlan 40,将每个交换机的fa0/1-3,fa0/4-6,fa0/7-9,fa0/10-12 分别分配给以上四个 vlan，再在三层交换机上进行配置，要求实现不同 vlan 之间能够互访。一、拓扑图二、交换机的配置1、switch0 的配置SwitchenSwitch#vlan database% Warning: It is recommended to configure VLAN from config mode,as VLAN
