单臂路由

实验目的：实现不同vlan之间的通信

拓扑图：

 

 

实验步骤：

1.switch0的配置

Switch>en
Switch#conf
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#int f0/1
Switch(config-if)#sw
Switch(config-if)#switchport mo
Switch(config-if)#switchport mode tr
Switch(config-if)#switchport mode trunk   将端口设为trunk模式

Switch#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.

Switch(vlan)#vlan 2    新建vlan2
VLAN 2 added:
    Name: VLAN0002
Switch(vlan)#vlan 3     新建vlan3
VLAN 3 added:
    Name: VLAN0003
Switch(vlan)#exit

Switch#conf
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#int fa0/2
Switch(config-if)#sw
Switch(config-if)#switchport ac
Switch(config-if)#switchport access vlan 2   将端口划到vlan 2上
Switch(config-if)#int fa0/3
Switch(config-if)#sw
Switch(config-if)#switchport ac
Switch(config-if)#switchport access vlan 3   将端口划到vlan 3上
Switch(config-if)#
Switch#

2.配置Route0

outer>
Router>en
Router#conf
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#int fa0/0
Router(config-if)#no shut

%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)#int fa0/0.2

%LINK-5-CHANGED: Interface FastEthernet0/0.2, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.2, changed state to up
Router(config-subif)#de
Router(config-subif)#en
Router(config-subif)#encapsulation do
Router(config-subif)#encapsulation dot1Q 2    封装协议
Router(config-subif)#ip add 172.168.10.1 255.255.255.0
Router(config-subif)#no shut
Router(config-subif)#int fa0/0.3
Router(config-subif)#
%LINK-5-CHANGED: Interface FastEthernet0/0.3, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.3, changed state to up

Router(config-subif)#en
Router(config-subif)#encapsulation do
Router(config-subif)#encapsulation dot1Q 3   封装协议
Router(config-subif)#ip add 172.168.20.1 255.255.255.0
Router(config-subif)#no shut
Router(config-subif)#

3.配置pc1、pc2的IP

PC1：172.168.10.2 255.255.255.0 GW172.168.10.1

PC2：172.168.20.2 255.255.255.0 GW172.168.20.1

4.测试在PC1上pingPC2

Packet Tracer PC Command Line 1.0
PC>ping 172.168.20.2

Pinging 172.168.20.2 with 32 bytes of data:
