三层交换机实现vlan间通信
Switch_3:
#en
#configure terminal
#vlan2
#vlan3
#int range fa0/1-2
#switchport mode access
#switchport access vlan2
#no shutdown
#int range fa0/2-3
#switchport mode access
#switchport access vlan3
#no shutdown
#int fa0/24
#switchport mode trunk
#switchport trunk allowed vlan all
#no shutdown
Switch_0:
#en
#configure terminal
#ip routing
#vlan 2
#vlan 3
#int vlan2
#ip add 192.168.1.1 255.255.255.0
#exit
#int vlan3
#ip add 192.168.2.1 255.255.255.0
#exit
#int fa0/24
#switchport mode trunk
#switchport trunk allowed vlan all
单臂路由实现vlan间通信
交换机和pc的配置都不变，以下是路由器的配置
#en
#configure terminal
#int fa0/0
#no shutdown
#exit
#int fa0/0.1
#encapsulaton dot1Q 2
#ip address 192.168.1.1 255.255.255.0
#exit
#int fa0/0.2
#encapsulation dot1Q 3
#ip address 192.168.2.1 255.255.255.0
#exit
#end
#show ip route
