Enabling VTP Version 2
VTP version 2 is disabled by default on VTP version 2-capable network devices. When you enable VTP
version 2 on a network device, every VTP version 2-capable network device in the VTP domain enables
version 2.
Caution VTP version 1 and VTP version 2 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 version 2
unless every network device in the VTP domain supports version 2.
