交换机不同接口分配不通过的IP地址

路由器上也要创建vlan，设置trunk，路由器型号为msr3620的话需要设备单臂路由，

路由器单臂路由配置

一、   组网图：

二、   路由器和交换机上面的配置：

#

interface GigabitEthernet0/1

 port link-mode route

#

interface GigabitEthernet0/1.1  //子接口1.1//

 vlan-type dot1q vid 4   //配置其子接口Vid为4//

 ip address 10.1.1.1 255.255.255.0  //设置下面vlan4内的客户端网关//

#

interface GigabitEthernet0/1.2  //子接口1.2//

 vlan-type dot1q vid 2

 ip address 10.1.2.1 255.255.255.0  //设置下面vlan2内的客户端网关//

#

interface GigabitEthernet0/1.3  //子接口1.3//

 vlan-type dot1q vid 3

 ip address 10.1.3.1 255.255.255.0  //设置下面vlan3内的客户端网关//

Return

交换机上面的配置：

#

vlan 1 to 4

#

interface Aux1/0/0

#

interface GigabitEthernet1/0/1  //和路由器互联口//

 port link-type trunk   //接口类型为TRUNK//

 port trunk permit vlan all  //允许所有vlan通过//

#

interface GigabitEthernet1/0/2

 port access vlan 2

#

interface GigabitEthernet1/0/3

 port access vlan 2

#

interface GigabitEthernet1/0/4
