实验二 通过路由器实现VLAN间通信
一、实验环境：Windows7操作系统的计算机；
Boson Netsim for CCNA v6.0
二、实验步骤;sw1的fa0/1接到pc1,sw1的fa0/2接到pc2,sw2的fa0/1接到pc3,sw1的fa0/2接到pc4,sw1的fa0/12接到sw2的fa0/12,rt1的fa0/1接到sw1的fa0/3.配置如下：
（1） 交换机Switch1配置如下:
Switch>enable
Switch#vlan database
Switch(vlan)#vtp domain yctc
Changing VTP domain from NULL to yctc Switch(vlan)#vtp server
Switch(vlan)#vlan 10 name zz VLAN 10 added: Name:zz
Switch(vlan)#vlan 20 name nn VLAN 20 added: Name:nn Switch(vlan)#exit APPLY completed. Exiting....
Switch#config t
Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#hostname switch1 switch1(config)#inter fa0/1
switch1(config-if)#switchport mode access switch1(config-if)#switchport access vlan 10 switch1(config-if)#inter fa0/2
switch1(config-if)#swwitchport mode access ^
% Invalid input detected at '^' marker.
switch1(config-if)#switchport mode access switch1(config-if)#switchport access vlan 20 switch1(config-if)#inter fa0/12
switch1(config-if)#switchport mode trunk switch1(config-if)#inter fa0/3
switch1(config-if)#switchport mode trunk
（2） 交换机Switch2配置如下:
Switch>enable
Switch#vlan database
Switch(vlan)#vtp domain yctc
Changing VTP domain from NULL to yctc Switch(vlan)#vtp client Switch(vlan)#exit APPLY completed. Exiting....
Switch#config t
Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#hostname switch2 switch2(config)#inter fa0/1
switch2(config-if)#switchport mode access switch2(config-if)#switchport access vlan 10 switch2(config-if)#inter fa0/2
switch2(config-if)#switchport mode access switch2(config-if)#switchport access vlan 20 switch2(config-if)#inter fa0/12
switch2(config-if)#switchport mode trunk switch2(config-if)#
PC1:
192.168.10.2 255.255.255.0 192.168.10.1 PC2:
192.168.20.2 255.255.255.0 192.168.20.1 PC3:
192.168.10.3 255.255.255.0 192.168.10.1 PC4:
192.168.20.3 255.255.255.0 192.168.20.1
（3）路由器配置：
Router>enable Router#conifg t ^
% Invalid input detected at '^' marker.
Router#config t
Enter configuration commands, one per line. End with CNTL/Z. Router(config)#inter fa0/3 Invalid Command
Router(config)#inter fa0/0
Router(config-if)#no ip address Router(config-if)#no shut
%LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up Router(config-if)#exit
Router(config)#int fa0/0.10 Router(config-subif)#
Router(config-subif)#enca dotlq 10 ^
% Invalid input detected at '^' marker.
Router(config-subif)#enca dot1q 10
Router(config-subif)#ip address 192.168.10.1 255.255.255.0 Router(config-subif)#exit Router(config)#int fa0/0.20
Router(config-subif)#enca dot1q 20
Router(config-subif)#ip address 192.168.20.1 255.255.255.0 Router(config-subif)#exit Router(config)#
三、最终配置列表：
Router1 Switch1 Switch2 PC1 PC1 PC1 PC1 子端口 192.168.10.1 Vlan10 Vlan10 子端口 192.168.20.1 Vlan20 Vlan20 Ethernet ip 子网掩255.255.255.0 码 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0
