If in a already converged STP network if we introduce a new switch with lower priority will it force the full network to run the STP all again?
Or STP will hold the currently elected root as the root bridge even after adding a new switch with lower priority? In this case how do we force all switches in the network to recalculate new root bridge? Does this recalculation has a big impact on network or it is recomended to do the activity only with scheduled down time?
Please share the experience.
Any link on cisco.com?
Thanks in advance
