Hi,
I am new to ryu.I am using the RYU controller to control my mininet
topology.My mininet topology is given below.

I start the topology as follows.

sudo python custom/topo-onos-2.py

After starting the controller when I start my switches the messages that I
get on the controller are as follows.

It seems to be recieving packet-in messages?I don't expect packe-in
messages as I am not sending any data across the switches?
Can some one kindly enlighten me as to what is happening here.
Thanks & Regards,
Karthik.
