Hi,
I have a question about RYU and OpenStack.
I have already succeeded in setting up OpenStack with RYU plugin.
There are 3 compute nodes, 1 network node, 1 controller node.
My data network is that 3 compute nodes and 1 network node connect to one
legacy switch(172.16.0.0/24), and my management network is that all nodes
are connect to one switch(192.168.3.0/24). These settings are great for me.
However, I want to see the efficiency by replacing legacy switch to
OpenFlow switch in my data network. After I set controller IP to OpenFlow
Switch, and I try to ping one compute node to another, something strange
happened. The OpenFlow Controller I run on controller node print sequence
of messages:

EVENT PortSet->GRETunnel EventOFPPacketIn
packet in ev <ryu.controller.ofp_event.EventOFPPacketIn object at

I want to figure out whether I can use real OpenFlow switch in my data
network.
My technology is GRE tunneling, I also wonder that if VLAN or MAC address
based L2 isolation can use OpenFlow switches in data network.
my
RYU_APPS=ryu.app.gre_tunnel,ryu.app.quantum_adapter,ryu.app.rest,ryu.app.rest_conf_switch,ryu.app.rest_tunnel,ryu.app.tunnel_port_updater,ryu.app.rest_quantum,ryu.app.rest_conf_switch
I don't know if I miss some apps?
THX!!!!
