客户机配置：
PC1：
属于vlan2成员，与SW1的F0/2口相连
IP:10.0.0.1/24
PC2:
属于VLAN2成员，与SW3的F0/2口相连
IP:10.0.0.2/24
测试：
PC1#ping 10.0.0.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 72/140/192 ms
总结：
transparent(透明)模式可以转发同一域名下的VTP信息(vtp version 1)，但不学习VTP信息。可以创建、删除、修改VLAN，但只在本地有效。透明模式在VTP VERSION 2下可以转发不同域名的VTP信息。
