單臂路由實驗

實驗條件：
switch 1pc : 2960-24TT
router 1pc : 2811
pc1：
192.168.1.100
255.255.255.0
192.168.1.1

pc2：
192.168.2.100
255.255.255.0
192.168.2.1

先配連接兩個pc的switch端口0/1, 0/2的vlan

Switch#configure  t                                                                                    #配置模式
Switch(config)#vlan 100                                                                            #建立vlan 100
Switch(config-vlan)#exit               
Switch(config)#interface fastEthernet 0/1                                           #指定port
Switch(config-if)#switchport access vlan 100                                      #指定port為vlan 100
Switch(config-if)#spanning-tree portfast

Switch#configure  t                                                                                    #配置模式
Switch(config)#vlan 200                                                                            #建立vlan 200
Switch(config-vlan)#exit                                                            
Switch(config)#interface fastEthernet 0/2                                           #指定port
Switch(config-if)#switchport access vlan 200                                      #指定port為vlan 200
Switch(config-if)#spanning-tree portfast

配置switch連接router的端口0/3為trunk模式。

Switch#conf t
Switch(config-if)#int fa 0/3
Switch(config-if)#switchport mode trunk                                                #指定端口做trunk
這時在不同vlan中的pc是無法ping通的。因為，沒有配置路由。

 ***switch 操作結束***
