等于核心下联两个普通交换机
核心配置vlan10 20 30 40
设置ip vlan10 10.0.1.1/24
interface vlan 10
ip address 10.0.1.1 255.255.255.0
interface vlan 20
ip address 10.0.2.1 255.255.255.0
interface vlan 30
ip address 10.0.3.1 255.255.255.0
interface vlan 40
ip address 10.0.4.1 255.255.255.0
核心下联到普通交换机的接口配置成trunk 然后允许所有vlan通过
普通交换机上联核心交换机的接口液配制成trunk 然后允许所有vlan通过
普通交换机创建vlan，10.20.30.40
将接口划分到相应的vlan
pc的网关设置成10.0.X.1
ok 了
很简单，在三层交换机上起4个vlan，配置4个SVI接口地址，打开ip routing，普通交换机把网关指向三层交换机即可实现四台不同vlan电脑之间的通信
你的普通交换机支持VLAN吗？
支持就可以做
反正就是交换机连接的接口用trunk口，PC用ACCESS口
有1台三层交换机做SVI即可
