需要通过单臂路由才能是不同的vlan之间通信，具体配置就是进入子接口中封装802.1Q协议配置vlan的IP地址并且no shutdownRouter(config)#interface f0/0.1%LINK-5-CHANGED: Interface FastEthernet0/0.1, changed state to up%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.1, changed state to upRouter(config-subif)#enRouter(config-subif)#encapsulation doRouter(config-subif)#encapsulation dot1Q ?
