The switch with the lowest Bridge ID (switch C) was elected the root bridge, and
the ports were selected to give a high port cost between switches B and C. The
two (optional) Gigabit ports (default port cost = 4) on switch A are connected to
one (optional) Gigabit port on both switch B and C. The redundant link between
switch B and C is deliberately chosen as a 100 Mbps Fast Ethernet link (default
port cost = 19). Gigabit ports could be used, but the port cost should be
increased from the default to ensure that the link between switch B and switch C
is the blocked link.
