Hello Jamo, Yes exactly, I have one instance of mininet running that should be connected to 3 opendaylight controllers. In my mininet python script i have defined that controllers should connect on 6653, 7753 and 8853 openflow ports. This should be somehow configured also in my opendaylight controllers for it to connect. I have tried changing port numbers in default(and legacy)-openflow-connection-config.xml for the 3 different opendaylight controllers and ports 8081/8080 for jetty.xml so they don’t collide but still I get the errors and the 2 other controllers cannot connect to my mininet instance.
As a brief example just to make sure that my idea is clear: i run a mininet instance of 6 switches where each controller should only see/monitor/connect to 2 of the switches. Thank you for your response. ________________________________ From: Jamo Luhrsen <[email protected]> Sent: Thursday, February 8, 2018 12:57:26 AM To: Mohamed Abdel Metaal; [email protected]; openflowplugin-dev Subject: Re: [OpenDaylight Discuss] Multiple Controller implementation adding the openflowplugin-dev list here as well. Mohamed, I don't get the impression that your OpenDaylight controllers are in a clustering setup. Is that correct? I'm not totally following what you are trying to accomplish. You have just one mininet instance connecting to a single IP address, but you want the switches in that single mininet instance to somehow be distributed across multiple (3) OpenDaylight controllers? Can you elaborate a little more please?
