Then, the following image appears.
The root bridge of the spanning tree is the bridge with the lowest bridge ID. Each bridge has a
unique identifier (ID) and a configurable priority number; the
Bridge ID contains both numbers. To
compare two bridge IDs, the priority is compared first. If two bridges have equal priority, then the
MAC addresses are compared. For example, if switches A (MAC=0002ab111111) and B
(MAC=0002ab212121) both have a priority of 8000, then switch A will be selected as the root
bridge (it has the lower value MAC address). If the network administrators would like switch B to
become the root bridge, they must set its priority to be less than 8000.
Spanning tree computes its path by following the path of least cost, i.e., a path from the device to
the root that has minimum cost among all paths from the device to the root. The cost of traversing
a path is the sum of the costs of the segments on the path. The port connecting to that path
