同一路由器不同vlan之间的通信

第一步，看拓扑图。

先把pc上的ip都配好。开始设置

switch0：

>en

>conf t

>vlan 2

>exit

>int fa 0/1

>switchport access vlan 2

>exit

>int fa 0/2

>switchport access vlan 2

>exit

>int fa 0/3

>switchport mode trunk

>end

switch1:

>en

>conf t

>vlan 3

>exit

>int fa 0/1

>switchport access vlan 3

>exit

>int fa 0/2

>switchport access vlan 3

>exit

>int fa 0/3

>switchport mode trunk

>end

Router0:

>enable

>configure terminal

>interface fastEthernet 0/0

>no ip adderss //清除ip

>no shutsown

>exit

>interface fastEthernet 0/0.1 //子接口设置

>encapsulation dot1Q 2 //封装协议 连到vlan 2

>ip address 192.168.0.1 255.255.255.0

>exit

>interface fastEthernet 0/1

>no ip adderss //清除ip

>no shutsown

>exit

>interface fastEthernet 0/1.1 //子接口设置

>encapsulation dot1Q 3 //封装协议 连到vlan 3

>ip address 192.168.1.1 255.255.255.0

>end

pc0 CMD:

ping PC1

ping PC 3
