Assuming that we are still talking about single identifier for IP and MAC,
why does it affect the working of spanning tree at all? The spanning tree
algorithm does not care whether an end station has two different identifiers
(IP and MAC different) or just one identifier (IP=MAC). In fact, the STA
does not care whether there are any end stations at all!
