lowest's... the best configuration bpdu determination
lowest switch id
lowest path cost to root
lowest sender bid
lowest sender port id

a root port for every non-root switch in the tree
a designated switch for every lan segment
a designated port for each segment's designated switch
loops are prevented in redundant paths
of course, convergence is complete when all ports in the tree are forwarding or blocking
