（原）Cisco三层交换机SVI（VLAN间路由）

PC0和PC1分别处在不同VLAN，需通过3层交换机SVI接口实现VLAN间通信

2层交换机配置

vlan 11

 exit

vlan 12

 exit

interface Vlan11

 ipaddress 11.1.1.1 255.255.255.0

!

interface Vlan12

 ipaddress 12.1.1.1 255.255.255.0

!

interface FastEthernet0/1

 switchport mode trunk

 switchport trunk allowed vlan all

 noshutdown

 exit
