VLAN 路由实验图解(交换机为cisco1900系列)
注：
PC1：192.168.1.2 255.255.255.0
PC2：192.168.2.2 255.255.255.0
PC3：192.168.1.3 255.255.255.0
PC4：192.168.2.3 255.255.255.0
Fa0/0.1：192.168.1.1 255.255.255.0
Fa0/0.2：192.168.2.1 255.255.255.0
配置VLAN路由应该注意：
路由器必须是Cisco2620以上版本，支持快速以太网接口和VLAN路由模块；
配置时路由器的子端口必须和一个VLAN相对应；
配置交换机时要开启干道传输。
