客戶機配置：

PC1：

屬于vlan2成員，與SW1的F0/2口相連

IP:10.0.0.1/24

PC2:

屬于VLAN2成員，與SW3的F0/2口相連

IP:10.0.0.2/24

測試：

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

總結：

transparent(透明)模式可以轉發同一域名下的VTP資訊(vtp version 1)，但不學習VTP資訊。可以建立、删除、修改VLAN，但隻在本地有效。透明模式在VTP VERSION 2下可以轉發不同域名的VTP資訊。
