1.單臂路由(圖)
環(huán)境:一臺(tái)路由器,一臺(tái)二層交換機(jī),兩臺(tái)pc機(jī)
二層交換機(jī)的配置
一般模式:
Switch》
輸入enable進(jìn)入特權(quán)模式:
Switch》enable
輸入configure terminal進(jìn)入全局配置模式:
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
創(chuàng)建vlan 10 和 vlan 20:
Switch(config)#vlan 10
Switch(config-vlan)#vlan 20
Switch(config-vlan)# exit
進(jìn)入接口配置模式:
Switch(config)#interface fastEthernet 0/1
把0/1變成trunk口(默認(rèn)是access口)
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
進(jìn)入接口配置模式分別把對(duì)應(yīng)的接口,加入對(duì)應(yīng)的vlan:
Switch(config)#interface fastEthernet 1/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
Switch(config-if)#interface fastEthernet 2/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 20
到此而層交換機(jī)配置完畢!
路由器的配置:
Router》
Router》enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#inter fas 0/0
Router(config-if)#no ip address
Router(config-if)#no shutdown

Router(config-subif)#encapsulation dot1Q 10
注意:在配置ip時(shí)一定要先封裝802.1q協(xié)議
Router(config-subif)#ip address 192.168.10.1 255.255.255.0
Router(config-subif)#no shutdown
Router(config-subif)#int fas 0/0.20
%LINK-5-CHANGED: Interface FastEthernet0/0.20, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.20, changed state to up
Router(config-subif)#ip address 192.168.20.1 255.255.255.0
% Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q,
or ISL vLAN.
Router(config-subif)#encapsulation dot1Q 20
Router(config-subif)#ip address 192.168.20.1 255.255.255.0
Router(config-subif)#no shutdown
Router(config-subif)#
查看路由表:
