VTP - Multiple Servers with VTP version 2
When configuring VTP, the behavior of the VTP server(s) will depend upon the version being used. When using VTP version 2, it is possible to configure more than one switch as a VTP Server. All VTP 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.
This is in contrast the single primary server that is used with VTP version 3.
