单臂路由配置步骤

1、创建vlan

Switch3(config)#vlan 2

Switch3(config)#name guo

Switch3(config)#vlan 3

Switch3(config)#name shi

Switch4(config)#vlan 2

Switch4(config)#name guo

Switch4(config)#vlan 3

Switch4(config)#name shi

2、将端口加入vlan

Interface Fa0/1

Switch3(config-if)#switchport mode access

Switch3(config-if)#switchport access vlan 2

Interface Fa0/2

Switch3(config-if)#switchport access vlan 3

Switch4(config-if)#switchport mode access

Switch4(config-if)#switchport access vlan 2

Switch4(config-if)#switchport access vlan 3

3、创建Trunk

Switch3(config)#interface range fastEthernet 0/3-5

Switch3(config)#switchport mode trunk

Switch4(config)#interface range fastEthernet 0/3-4

Switch4(config)#switchport mode trunk

4、配置VTP

Switch3(config)#vtp domain wei

Switch3(config)#vtp mode server

Switch3(config)#vtp password 123

Switch4(config)#vtp domain wei

Switch4(config)#vtp mode client

Switch4(config)#vtp password 123

5、封装dot1q

Router2(config)#interface fastEthernet 0/0

Router2(config-if)#no shut

Router2(config-if)#exit

Router2(config)#interface fastEthernet 0/0.2

Router2(config-subif)#encapsulation dot1Q 2

Router2(config-subif)#ip address 192.168.1.1 255.255.255.0

Router2(config-subif)#no shut

Router2(config)#interface fastEthernet 0/0.3

Router2(config-subif)#encapsulation dot1Q 3

Router2(config-subif)#ip address 192.168.2.1 255.255.255.0

6、测试
