实验过程：
第一步：在 SW1上配置VTP
sw1#vlan da
sw1(vlan)#vtp domain ccie
Changing VTP domain name from ccna to ccie
sw1(vlan)#vtp s
sw1(vlan)#vtp server
Device mode already VTP SERVER.
sw1(vlan)#exit
APPLY completed.
Exiting....
第二步：在R2上配置VTP
sw2(vlan)#vtp domain ccie
Changing VTP domain name from ccna to ccie
sw2(vlan)#vtp c
sw2(vlan)#vtp client
Setting device to VTP CLIENT mode.
sw2(vlan)#exit
In CLIENT state, no apply attempted.
Exiting....
第三步：在SW1上配置Trunk中继接口
Enter configuration commands, one per line. End with CNTL/Z.
sw1(config)#int f0/23
sw1(config-if)#switchport mo tr
//配置交换机端口为trunk
sw1(config-if)#sw tr en dot1q
//封装类型为802.1q
sw1(config-if)#sw tr all vlan all
//允许通过所有vlan
第四步：在SW2上配置trunk中继接口
sw2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
sw2(config)#int f0/23
sw2(config-if)#sw mo trunk
sw2(config-if)#switchport trunk encapsulation dot1q
第五步：在SW1上创建vlan
sw1(vlan)#vlan 4 name 4
VLAN 4 modified:
Name: 4
sw1(vlan)#vlan 5 name 5
VLAN 5 modified:
Name: 5
sw1(vlan)#
第六步：在SW1上验证帧中继接口
sw1#sh int f0/23 sw
Name: Fa0/23
Switchport: Enabled
Administrative Mode: trunk
Operational Mode: trunk
Administrative Trunking Encapsulation: dot1q
Operational Trunking Encapsulation: dot1q
Negotiation of Trunking: On
Access Mode VLAN: 1 (default)
Trunking Native Mode VLAN: 1 (default)
Administrative Native VLAN tagging: enabled
第七步：到帧中继上查看是否学习到
sw2# sh vlan
