VTP transparent switches do not participate in VTP. A VTP transparent switch does not advertise its VLAN configuration and does not synchronize its VLAN configuration based on received advertisements. However, in VTP Version 2, transparent switches do forward VTP advertisements that they receive from other switches through their trunk interfaces. You can create, modify, and delete VLAN’s on a switch in VTP transparent mode
Interestingly, and I shall test it shortly, on some study material I reviewed a while back one of the instructors stated that VTP Version 1 did actually pass on the advertisement if the switch was in Transparent mode.
