Hi Vardhan, Please keep the mailing list. Ryu-devel <ryu-devel@lists.sourceforge.net>
> but it still doesn't use the dpid which I configured. From the log, it seems 4 switches are in your topology as following. [STP][INFO] dpid=0000000000000004: Join as stp bridge. [STP][INFO] dpid=0000000000000003: Join as stp bridge. [STP][INFO] dpid=00000010f33aca7b: Join as stp bridge. [STP][INFO] dpid=00000010f33acb09: Join as stp bridge. You mean "dpid=0000000000000004 and dpid=0000000000000003 should not join into STP network", right? If so, simple_switch_stp.py joins all the switch which connecting to the conntroller into STP network. Even if you omit stplib.Stp.set_config() for the particular switch, the switch is configured by the default value.
