All switches in a VTP domain must run the same VTP version.
A VTP version 2-capable switch can operate in the same VTP domain as a switch running VTP
version 1 if version 2 is disabled on the version 2-capable switch. Version 2 is disabled by default.
Do not enable VTP version 2 on a switch unless all of the switches in the same VTP domain are
version-2-capable. When you enable version 2 on a switch, all of the version-2-capable switches in
the domain enable version 2. If there is a version 1-only switch, it will not exchange VTP
information with switches with version 2 enabled.
If there are Token Ring networks in your environment (TRBRF and TRCRF), you must enable VTP
version 2 for Token Ring VLAN switching to function properly. To run Token Ring and Token
Ring-Net, disable VTP version 2.
Enabling or disabling VTP pruning on a VTP server enables or disables VTP pruning for the entire
VTP domain.
