Using the bridge ID as a tie-breaker
After exchanging BPDUs with other switches, a switch might find that two paths have
the same lowest cost. In this case, the switch uses the bridge ID of its STP neighbors
as a tie-breaker. The neighbor with the lowest bridge ID has the lowest-cost path to
the root bridge.
In the network below, for example, Switch D has two paths to the root bridge and
both have a path cost of 4,000. Switch A has the next priority in the root path.
