Hi,

I'm building a OpenStack using Ryu-Plugin.
It is OpenStack environment using physical switches as shown in the figure 
below.
But Ryu controller does not seem to be controlled correctly the physical switch.

A physical switch is set up as L2 switch, communication between Controller - 
Compute will be performed.
But a Ryu controller setup is performed by considering a physical switch as an 
OpenFlow switch,
flow registration will not be performed but a packet will be droped.

Is Ryu Plugin supporting such composition ?
What should I do to operate it well?


[OpenStack environment]
-OpenStack Grizzly
-CENTEC V350 set version OpenFlow1.0
-Ryu Plugin v3.3 (https://github.com/osrg/ryu)
