路由器配制

			
Router#configure terminal

Router(config)#interface f0/0

Router(config-if)#no shutdown

Router(config-if)#interface f0/0.1 --------------- 创建子接口1

Router(config-subif)#encapsulation dot1q 2  ------ 2为VLAN号 对应VLAN 2

Router(config-subif)#ip address 10.10.11.1 255.255.255.0

Router(config-if)#interface f0/0.2 ---------------- 创建子接口2

Router(config-subif)#encapsulation dot1q 3  ------- 3为VLAN号 对应VLAN 3

Router(config-subif)#ip address 10.10.10.1 255.255.255.0

路由器已经配制完毕，可以在Router#show run 看一下当前的配制，用Router#show interfaces 看当前端口的状态，f0/0.1 和f0/0.2两个子

接口是否为up状态。
			
			

交换机配制

			
Switch#vlan database

Switch(vlan)#vlan 2  name 财务部 ------- 创建vlan 2为财务部

Switch(vlan)#vlan 3 name  市场部----------创建vlan 3为市场部

Switch(vlan)#exit

Switch configure terminal

Switch(coning)#interface  range f0/2 - 9

Switch(coning-if)#switch port access vlan 2 ------- 将f0/-f0/9端口分到vlan 2中

Switch(config-if)#interface range f0/10 - 14

Switch(config-if)#switchport access vlan 3 --------将端f0/10至f0/14口3分到vlan 3中

Switch(config-if)#interface f0/1

Switch(config-if)#switchport trunk encapsulation dot1q ------将端口封装

Switch(config-if)#switchport mode trunk  -------- 将端口配制为trunk模式
			
			

客户端配制：

			
WorKstation 1 配制为：10.10.11.3 255.255.255.0 网关：10.10.11.1
Workstation 2 配制为：10.10.10.3 255.255.255.0 网关：10.10.10.1
			
			

3560交换机VLAN间路由的具体设置

路由, VLAN, 交换机, 设置 在3560交换机上划三个VLAN，并且要求其中两个VLAN间能够互相访问，操作如下，请指点：
