I currently have 2 6509 switches at the core of my network acting in a redundant manner. For my L2 vlans, the primary 6509 switch is setup as a priority of 4096, and my secondary 6509 of 8192, both are configured at VTP servers. Not sure if this is best practice or not. I want to bring a 3rd 6509 online in another building to act as a 3rd 6509 core in the event the other 2 go down, or the connection between the building is lost. Should I configure this one as a vtp server as well, and set the priority to 16384?
