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。

配置:
