1、配置交換機vtp

SW1：dom

SW1>enable
SW1#config t
Enter configuration commands, one per line.  End with CNTL/Z.
SW1(config)#hostname SW1 
SW1(config)#vlan 10
SW1(config-vlan)#exit
SW1(config)#vlan 20
SW1(config-vlan)#exit
SW1(config)#vtp mode server      //配置sw1爲服務器端
Device mode already VTP SERVER.
SW1(config)#vtp domain cisco       //配置vtp 的域名爲Cisco
Domain name already set to cisco.
SW1(config)#vtp password cisco123  //配置密碼
Password already set to cisco123
SW1(config)#service password-encryption   //明文密碼加密
SW1(config)#interface f0/1
SW1(config-if)#switchport mode trunk  //配置兩交換機間鏈路模式爲trunk
SW1(config-if)#switchport trunk allowed vlan all 
SW1(config-if)#no shutdown
SW1(config-if)#exit
SW1(config)#interface f0/2
SW1(config-if)#switchport mode access
SW1(config-if)#switchport access vlan 10
SW1(config-if)#no shutdown
SW1(config-if)#exit
SW1(config)#interface f0/3
SW1(config-if)#switchport mode trunk  //配置路由器與交換機相連鏈路爲trunk
SW1(config-if)#switchport trunk allowed vlan all 
SW1(config-if)#no shutdown
SW1(config-if)#exit
SW1(config)#

sw2:ide

SW2>enable
SW2#config t
Enter configuration commands, one per line.  End with CNTL/Z.
SW2(config)#hostname SW2
SW2(config)#vtp mode client
Device mode already VTP CLIENT.
SW2(config)#vtp domain cisco    //配置sw2爲vtp客戶端模式
Domain name already set to cisco.
SW2(config)#vtp password cisco123  //配置密碼
Password already set to cisco123
SW2(config)#service password-encryption  //明文密碼加密
SW2(config)#interface f0/1
SW2(config-if)#switchport mode trunk
SW2(config-if)#switchport trunk allowed vlan all 
SW2(config-if)#no shutdown 
SW2(config-if)#exit
SW2(config)#interface f0/2
SW2(config-if)#switchport mode access
SW2(config-if)#switchport access vlan 20
SW2(config-if)#no shutdown
SW2(config-if)#exit
SW2(config)#

2、在SW2上查看，是否學習到相應的VLAN

SW2(config)#do show vlan

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------

                                                Fa0/11, Fa0/12, Fa0/13, Fa0/14
                                                Fa0/15, Fa0/16, Fa0/17, Fa0/18
                                                Fa0/19, Fa0/20, Fa0/21, Fa0/22
                                                Fa0/23, Fa0/24, Gig1/1, Gig1/2

Remote SPAN VLANs

SW2(config)#

由查看結果可知，SW2交換機已從SW1交換機學習到了VLAN 10和VLAN 20。學習

3、配置路由器子接口

AR1:測試

AR1>enable
AR1#config t
Enter configuration commands, one per line.  End with CNTL/Z.
AR1(config)#hostname AR1
AR1(config)#interface g0/0   //進入物理接口
AR1(config-if)#no shutdown  //啓用該接口
AR1(config-if)#interface g0/0.10  //進入子接口
AR1(config-subif)#encapsulation dot1q 10  // 將子接口封裝到VLAN 10中
AR1(config-subif)#ip address 192.168.10.254 255.255.255.0  
//配置IP地址
AR1(config-subif)#no shutdown   //啓用子接口
AR1(config-subif)#exit
AR1(config)#interface g0/0.20
AR1(config-subif)#encapsulation dot1q 20   //將子接口封裝到VLAN 20中
AR1(config-subif)#ip address 192.168.20.254 255.255.255.0
AR1(config-subif)#no shutdown
AR1(config-subif)#exit
AR1(config)#
