Hi,

VTP version1 and VTP version2 are not interoperable on network devices in the same VTP domain. Every network device in the VTP domain must use the same VTP version. Do not enable VTP version2 unless every network device in the VTP domain supports version2, accordingly your solution is to configure both to run Version 1.

HTH, please do rate all helpful replies,

Mohammed Mahmoud.
