## Vlan间路由 ##

**方式一：使用路由器实现单臂路由（子接口）**  
实验拓扑：

一、配置sw1  
Switch>ena  
Switch\#conf  
Configuring from terminal, memory, or network \[terminal\]?  
Enter configuration commands, one per line. End with CNTL/Z.  
Switch(config)\#vlan 10  
Switch(config-vlan)\#vlan 20  
Switch(config-vlan)\#exit  
Switch(config)\#int f0/1  
Switch(config-if)\#sw acc vlan 10  
Switch(config-if)\#int f0/2  
Switch(config-if)\#sw acc vlan 20  
Switch(config-if)\#int f0/3  
Switch(config-if)\#sw mode trunk  
Switch(config-if)\#

**二、配置router0**  
Router>ena  
Router\#conf  
Configuring from terminal, memory, or network \[terminal\]?  
Enter configuration commands, one per line. End with CNTL/Z.  
Router(config)\#int f0/0 进入物理接口  
Router(config-if)\#no shu 开启端口  
Router(config-if)\#exit  
Router(config)\#int f0/0.10 配置子接口  
Router(config-subif)\#encapsulation8 dot1Q 10 封装协议，必须与vlan ID号相对应  
Router(config-subif)\#ip address 192.168.10.254 255.255.255.0 配置vlan10的网关  
Router(config-subif)\#int f0/0.20 配置子接口  
Router(config-subif)\#encapsulation dot1Q 20 封装协议，必须与vlan ID号相对应  
Router(config-subif)\#ip address 192.168.20.254 255.255.255.0 配置vlan20的网关  
Router(config-subif)\#do show ip int b 查看端口IP配置信息

**三、自行配置主机IP地址(记得配置网关)**

**四、测试：PC0 ping PC1**

成功！就这样做。

**方式二：使用三层交换机实现单臂路由（SVI接口）**  
实验拓扑：

Switch(config-if)\#int f0/2  
Switch(config-if)\#sw acc vlan 20  
Switch(config-if)\#int f0/3  
Switch(config-if)\#sw mode trunk  
Switch(config-if)\#

**二、配置三层交换机**  
Switch>ena  
Switch\#conf  
Configuring from terminal, memory, or network \[terminal\]?  
Enter configuration commands, one per line. End with CNTL/Z.  
Switch(config)\#vlan 10 创建相应的vlan10  
Switch(config-vlan)\#vlan 20 创建相应的vlan20  
Switch(config-vlan)\#exit  
Switch(config)\#int vlan 10 配置vlan10的SVI接口  
Switch(config-if)\#ip address 192.168.10.254 255.255.255.0 配置网关  
Switch(config-if)\#no shu 开启接口  
Switch(config-if)\#int vlan 20 配置vlan20的SVI接口  
Switch(config-if)\#ip address 192.168.20.254 255.255.255.0 配置网关  
Switch(config-if)\#no shu  
Switch(config-if)\#exit  
Switch(config)\#ip routing 开启路由功能  
Switch(config)\#do show ip int b 查看端口信息
