不同VLAN之间互访

1、不同VLAN之间互访 作者: 日期：利用三层交换机实现不同VLAN之间的互访交换机 switch。和 switchl 仓建 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、 switch。的配置Switch>enSwitch#vlan database% Warning: It is recommended to configure VLAN from co
