Hi Vardhan,
Thank you for sending the log. It seemed that dpid is not matching. > EVENT ofp_event->stplib EventOFPStateChange > [STP][INFO] dpid=0000000000000004: Join as stp bridge. > [STP][INFO] dpid=0000000000000002: Join as stp bridge. > [STP][INFO] dpid=0000000000000001: Join as stp bridge. ... > EVENT ofp_event->stplib EventOFPStateChange > [STP][INFO] dpid=00000010f33acb09: Join as stp bridge. ... Please remove the following comment-out and specify dpid in accordance with your environment. (https://github.com/osrg/ryu/blob/master/ryu/app/simple_switch_stp.py#L38-L47) Because simple_switch_stp.py is the sample application, dpid needs to be specified.
