I am upgrading an old network and as I add switches, I would like them to run rapid-pvst, instead of just pvst which is what the older switches are running.
Last I checked (with a Cisco techie at Networkers 2006), it was OK to have trunked switches with different modes (pvst and rapid-pvst)... but now I'm hearing differently from a few other sources.
Can someone please verify if this is a concern and if so, how should one proceed?
Cheers...
