    Spanning tree in the real world


      So as I get deeper in to the CCNP switch topics I've come across MST. In the CCNA world, RSTP seemed like it was god. If you have many VLANS it does not seem to make sense to run 1 instance of spanning tree per VLAN and most documents advise not to do that for obvious reasons. My question is what is actually used in the real world?? Are most networks running MST because that's just the best way to do it or are most just running RSTP because there just arent enough VLANS to make a difference?
