= designated bridge
Equal
port priority?
yes

no
Path with lowest
path costs = root path
Path with highest
no
priority (numerically
lower value) in bridge
identification = root path
Path with highest
no
port priority (numerically
lower value) = root path
Path with lowest
port number of designated
bridge = root path
