What is the convergence time for spanning tree ?

STP : 30 to 50 seconds

RSTP: usally less than 10 seconds , bu deafault 3*2 = 6 three default hello timers .

PVST : ?

PVST+:?

rapid pvst+:?

MST :?

Rapid PVST:?

Thanks 

can anyone kindly help..

Thanks

PVST, PVST+ = STP timers

MST + anything rapid = RSTP timers

Cant MST remember but heres the others

RSTP: from 2 up to 10 seconds

PVST : ? 30 - 50

PVST+: 30 - 50

rapid pvst+:? from 2 up to 10

MST :?

Rapid PVST:? from 2 up to 10

what is the default  convergence time for MSTP ?

[Jon Marshall]

I already said, MST uses RSTP so same convergence time.

In addition to what Jon and Mark have already noted, STP convergence time will also depend on a bit on the actual L2 topology and the devices involved. PVST+ convergence might also be impacted if you've enabled some of the rapid-STP like proprietary features (i.e. those optional features incorporated in the later rapid-STP standard).
