I am new to Ryu and trying to set it up with a physical switch connected to a VM on my computer. The switch's controller is set to 10.0.1.8 and I am trying to set the same on ryu controller. I used the following commands:

    sudo ovs-vsctl add-br br0
    sudo ovs-vsctl add-port br0 eth2
    sudo ovs-vsctl set bridge br0 10.0.1.8 protocols=OpenFlow13

Doing a netstat shows that ryu controller is still listening on 0.0.0.0 as per the output below. Can someone please assist me here?

    State       PID/Program name
    tcp        0      0 0.0.0.0:6633            0.0.0.0:*

It seems I had to include the --ofp-listen-host parameter and specify the controller IP there, as follows:

    PYTHONPATH=. ./bin/ryu-manager --verbose --ofp-listen-host 10.0.1.8 ryu/app/simple_switch.py

The commands I was using earlier apply only to a Mininet topology.
