I am not sure I full follow here: is this as simple as connect 2 switches to a first controller, the next 2 switches to a second controller and finally the last 2 switches to a third controller? if so there is nothing to do in controller, juts need to set mininet or OVS to do this, right? > > Thank you for your response. > > From: Jamo Luhrsen <[email protected] <mailto:[email protected]>> > Sent: Thursday, February 8, 2018 12:57:26 AM > To: Mohamed Abdel Metaal; [email protected] > <mailto:[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.
