The root bridge is also the designated bridge for each lan connected to
it, since the designated bridge is defined as the bridge which is closest
to the root bridge in a given LAN. (does this does make sense!?!?!?).
This is a little more complex in case multiple ports of the root brisge
are connected to the same lan... but that's a pathological case: instead
of "designated bridges" you can think of "designated ports"..
