VTP Version 3

Hello Azm

  1. In VTP version 3, you can configure more than one switch as a VTP Server, but only one switch can be the Primary Server at a time. The Primary Server is the only one that can create, modify, or delete VLANs. The other servers in VTP version 3 are in Secondary mode by default and only store the VLAN database but can’t modify it. If the Primary Server fails, you need to manually promote one of the Secondary Servers to Primary. Take a look at this NetworkLessons note about the primary VTP server and how it works for more info.

  2. In VTP version 2, you can also configure more than one switch as a VTP Server. All these servers can create, modify, or delete VLANs. However, it’s important to note that the last VLAN change made on any of the VTP Servers will be propagated to all other switches in the VTP domain.

I hope this has been helpful!
