Abstract
Starting a spanning tree protocol (STP) process in a network device excludes performing a root bridge election sequence. The network device receives and learns the STP roles and STP states of its ports based on the received bridge protocol data units (BPDUs) during a quiescent period of time subsequent to starting STP processing. Port role and port state learning occur absent the generation and transmission of BPDUs during the quiescent period of time. Subsequent to the end of the quiescent period, the network device commences generating and transmitting BPDUs.
