Cisco Packet Tracer---单臂路由
1.主机设置
PC0:192.168.1.2 VLAN 2 Fa0/1 192.168.1.1
PC1:192.168.2.2 VLAN 3 Fa0/2 192.168.2.1
PC2:192.168.1.3 VLAN 2 Fa0/1 192.168.1.1
PC3:192.168.2.3 VLAN 3 Fa0/2 192.168.2.1
2.交换机设置
Switch>ena
-------------------------生成vlan 2/3---------------------------
Switch#vlan database
Switch(vlan)#vlan 2
Switch(vlan)#vlan 3
Switch(vlan)#exit
-------------------------主机接端口设置且绑定vlan---------------------------
Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#int fa0/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 2
Switch(config-if)#exit
Switch(config)#int fa0/2
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 3
Switch(config-if)#exit
Switch(config)#exit
Switch#
----------------交换机接交换机端口设置且设置vlan全通all-------------------
Switch#conf t
Switch(config)#int fa0/3
Switch(config-if)#switchport mode trunk
Switch(config-if)#switchport trunk allowed vlan all
Switch(config-if)#
----------------交换机接路由器接口设置trunk且vlan全通all --------------------
Switch>ena
Switch#conf t
Switch(config)#int fa0/4
Switch(config-if)#switchport mode trunk
Switch(config-if)#switchport trunk allowed vlan all
Switch(config-if)#exit
Switch(config)#
3.路由器设置
Router>ena
-----------------设置路由器vlan 2/3，此处或许可无-----------------------
Router#vlan database
Router(vlan)#vlan 2
Router(vlan)#vlan 3
Router(vlan)#exit
-----------端口绑定ip及vlan设置-----------------------
Router#conf t
-------------进入与交换机相连端口并打开no shutdown----------------
Router(config)#int fa0/0
Router(config-if)#no shutdown
Router(config-if)#exit
----------创建子接口fa0/0.1对应vlan2并封装dot1Q协议---------------
Router(config)#int fa0/0.1
Router(config-subif)#encapsulation dot1q 2
Router(config-subif)#ip address 192.168.1.1 255.255.255.0
Router(config-subif)#exit
----------创建子接口fa0/0.2对应vlan3并封装dot1Q协议---------------
Router(config)#int fa0/0.2
Router(config-subif)#encapsulation dot1q 3
Router(config-subif)#ip address 192.168.2.1 255.255.255.0
Router(config-subif)#exit
4.测试跨网段互通PC0（VLAN2 192.168.1.2）ping PC1(VLAN 3 192.168.2.2)
