Hi Iwase, I sorted out the problem now only three switches join the Ryu stp, for which I have specified the dpid's. But they are still being disabled. I can't figure out why. Any insight or solution?

I can not say "Yes" with confidence. I think it's depending on your topology including the two extra switches, because they are connecting to the controller.
