Thanks for the info.

Hi,
VTP version 2 offers the following support options not available with version 1:
Unrecognized type-length-value (TLV) support-A VTP server or client propagates configuration changes to its other trunks, even for TLVs it is not able to parse. The unrecognized TLV is saved in NVRAM.
-------------------
Version-dependent transparent mode-In VTP version 1, a VTP transparent switch inspects VTP messages for the domain name and version and forwards a message only if the version and domain name match. Because only one domain is supported in the Supervisor engine software, VTP version 2 forwards VTP messages in transparent mode, without checking the version.
------------------------------
Consistency checks-In VTP version 2, VLAN consistency checks (such as VLAN names and values) are performed only when you enter new information through the command-line interface (CLI) or Simple Network Management Protocol (SNMP). Consistency checks are not performed when new information is obtained from a VTP message or when information is read from NVRAM. If the digest on a received VTP message is correct, its information is accepted without consistency checks.
I would conclude by saying that VTP version 1 and VTP Verision 2 can communicate if the domain names are the same. If they have diffrent domain names they will not communicate.
Hope this helps.
