上图：

首先给出上面给的IP：

R1：128.10.10.21/24 SW1：128.10.11.22/24

PC1：128.10.12.25/24 PC2：128.10.13.26/24 PC3：128.10.14.27/24

以下为R1的配置：

R1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
R1(config)#int f0/0
R1(config-if)#no sh
R1(config-if)#ip add 
*Mar  1 00:03:41.375: %LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up
*Mar  1 00:03:42.375: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
R1(config-if)#ip add 128.10.10.21 255.255.255.0
R1(config-if)#int f0/0.1
R1(config-subif)#enca
R1(config-subif)#encapsulation do
R1(config-subif)#encapsulation dot1Q 1
R1(config-subif)#ip add 128.10.11.1 255.255.255.0
R1(config-subif)#int f0/0.10
R1(config-subif)#encapsulation dot1Q 10          
R1(config-subif)#ip add 128.10.12.1 255.255.255.0
R1(config-subif)#int f0/0.20
R1(config-subif)#encapsulation dot1Q 20          
R1(config-subif)#ip add 128.10.13.1 255.255.255.0
R1(config-subif)#int f0/0.30                     
R1(config-subif)#encapsulation dot1Q 30          
R1(config-subif)#ip add 128.10.14.1 255.255.255.0
R1(config-subif)#end

以下为SW1的配置：

SW1#vlan database
SW1(vlan)#vlan 10
VLAN 10 added:
    Name: VLAN0010
SW1(vlan)#vlan 20
VLAN 20 added:
    Name: VLAN0020
SW1(vlan)#vlan 30
VLAN 30 added:
    Name: VLAN0030
SW1(vlan)#exit
APPLY completed.
Exiting....
SW1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
SW1(config)#no ip routing
SW1(config)#int vlan 1
SW1(config-if)#ip add 128.10.11.22 255.255.255.0
SW1(config-if)#int f0/1 
SW1(config-if)#sw
SW1(config-if)#switchport mo
SW1(config-if)#switchport mode a
SW1(config-if)#switchport mode access 
SW1(config-if)#sw
SW1(config-if)#switchport a
SW1(config-if)#switchport access vlan 10
SW1(config-if)#int f0/2
SW1(config-if)#switchport mode access   
SW1(config-if)#switchport access vlan 20
SW1(config-if)#int f0/3                 
SW1(config-if)#switchport mode access   
SW1(config-if)#switchport access vlan 30
SW1(config-if)#int f0/0
SW1(config-if)#sw
SW1(config-if)#switchport mo
SW1(config-if)#switchport mode tr
SW1(config-if)#switchport mode trunk 
SW1(config-if)#end

然后给PC的配置：（这里我只给PC1的配置）

PC1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
PC1(config)#no ip routing      //这里必须设置
PC1(config)#int f0/0
PC1(config-if)#no sh
PC1(config-if)#ip add
*Mar  1 00:08:58.091: %LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up
*Mar  1 00:08:59.091: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
PC1(config-if)#ip add 128.10.12.25 255.255.255.0
PC1(config-if)#end
