单臂路由

实验拓扑：

pc0属于vlan10 pc1属于vlan20

要求pc0和pc1能够相互通信

 

配置route

Router(config-if)#int f0/0.1

%LINK-5-CHANGED: Interface FastEthernet0/0.1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.1, changed state to upRouter(config-subif)#enc
Router(config-subif)#encapsulation dot1q ?
  <1-1005>  IEEE 802.1Q VLAN ID
Router(config-subif)#encapsulation dot1q 10
Router(config-subif)#ip add 192.168.21.1 255.255.255.0
Router(config-subif)#exit
Router(config)#int f0/0.2

%LINK-5-CHANGED: Interface FastEthernet0/0.2, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.2, changed state to upRouter(config-subif)#enc
Router(config-subif)#encapsulation dot1q 20
Router(config-subif)#ip add 192.168.32.2 255.255.255.0

配置switch

Switch(config)#int f0/1
Switch(config-if)#no sh
Switch(config-if)#switchp
Switch(config-if)#switchport mode trun
Switch(config-if)#switchport mode trunk

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
Switch(config-if)#exit
Switch(config)#exit
%SYS-5-CONFIG_I: Configured from console by console

Switch(config-if)#swi acc vlan 20

配置pc机

pc0的ip地址为10.10.10.10 255.255.255.0

网关为 192.168.21.1

pc1的ip地址为10.10.20.10 255.255.255.0

网关为 192.168.32.2
