Try it for yourself.
"To autonegotiate trunking, the interfaces must be in the same VTP
domain. Use the trunk or nonegotiate keywords to force interfaces in
different domains to trunk. For more information on VTP domains, see
"Understanding and Configuring VTP."
Trunk negotiation is managed by the Dynamic Trunking Protocol (DTP). DTP
supports autonegotiation of both ISL and 802.1Q trunks."

I do not believe that to be correct. For VLAN ID to propagate form a
server to a client, you ned the VTP domain to match.
For DTP to work on a trunk, one needs to be switchport dynamic auto
and the other end desirable. Trunk encapsulation will auto-negotiate
as well if left to the default.
DTP has nothing to do with VTP.

Let me clarify a bit further:
For DTP to form a trunk with the other end, your VTP domain needs to
match on both ends. This would be an instance where you need to set
the domain with a mode of transparent.

Hello GS,
just to clear this issue if i am running in VTP Transparent mode , do
i need
to make sure that the VTP domain name is the same or configure it at
all? i
feel there is no need since i am not running VTP, but can anyone think of
any situation where we need to configure the VTP domain name in
Transparent
mode .
TIA
