Bit,
VTP version 1 in transparent mode will make sure that the domain name &
version number matches before they can forward an advertisement. VTP version
2 in transparent mode will forward the advertisement without checking the
version number, but the domain name must match.
The VTP mode not withstanding, Cisco Switches will ignore advertisements
with different domain name and earlier configuration revision number.
HTH.
