STP (802.1D) is a bridge-based system that is used to implement parallel paths for network traffic.
STP uses a loop-detection process to:



Locate and then disable less efficient paths (i.e., paths that have a lower bandwidth).



Enable one of the less efficient paths if the most efficient path fails.

The figure

below shows a network made up of three LANs separated by three bridges. Each

segment uses at most two paths to communicate with the other segments. Since this configuration
can give rise to loops, the network will overload if STP is NOT enabled.

If STP is enabled, it will detect duplicate paths and prevent, or

block

, one of them from forwarding

traffic. In the following example, STP determined that traffic from LAN segment 2 to LAN
segment 1 should flow through Bridges C and A because this path has a greater bandwidth and is
therefore more efficient.
