I have 6509 for core switch and edge 3750. I have 30 vlans that distribuite with vtp and vtp pruning for avoid brodcast and another traffic generate to vlan. Which is the best solutions ? Vtp pruning or no vtp pruning but allowed only vlan that I need in the switch to the trunk port.
I don't think you will have problem with Rapid-PVST.
Its convergence time is much faster than that of the traditional STP.
