CISCO 单臂路由实验
拓扑图如下：
PC0在VLAN 10中，PC1在VLAN 20中，要求PC0能PING通PC1.
具体步骤如下：
1、在交换机上配置VLAN，并把接口加入到VLAN中。
sw>en
sw#vlan da
sw#vlan database
% Warning: It is recommended to configure VLAN from config mode, as VLAN database mode is being deprecated. Please consult user documentation for configuring VTP/VLAN in config mode.
sw(vlan)#vlan 10
VLAN 10 added:
Name: VLAN0010
sw(vlan)#vlan 20
VLAN 20 added:
Name: VLAN0020
sw(vlan)#exi
APPLY completed.
Exiting....
sw#config t
Enter configuration commands, one per line. End with CNTL/Z.
sw(config)#int range f0/1 - 5
sw(config-if-range)#sw
sw(config-if-range)#switchport ac
sw(config-if-range)#switchport access vlan 10
sw(config-if-range)#int range f0/6 - 10
sw(config-if-range)#sw
sw(config-if-range)#switchport acc
sw(config-if-range)#switchport access vlan 20
sw(config-if-range)#int f0/24
sw(config-if)#sw
sw(config-if)#switchport mo
sw(config-if)#switchport mode trunk
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/24, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/24, changed state to up
sw(config-if)#end

[OK]
2、在路由器上配置子接口，并封装802.1Q。
Router>en
Router#config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Router(config)#int f0/0
Router(config-if)#no sh
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
Router(config-if)#exi
Router(config)#int f0/0.1
%LINK-5-CHANGED: Interface FastEthernet0/0.1, changed state to up

Router(config-subif)#ip add 192.168.1.1 255.255.255.0
Router(config-subif)#no s
Router(config-subif)#int f0/0.2

Router(config-subif)#encapsulation dot1Q 20
Router(config-subif)#ip add 192.168.2.1 255.255.255.0
Router(config-subif)#en
% Ambiguous command: "en"
Router(config)#end
%SYS-5-CONFIG_I: Configured from console by console

[OK]
3、在PC上配置IP和网关，并检测结果；
PC>ping 192.168.1.2
Pinging 192.168.1.2 with 32 bytes of data:
Request timed out.
Reply from 192.168.1.2: bytes=32 time=111ms TTL=127
Reply from 192.168.1.2: bytes=32 time=125ms TTL=127
