I was trying to set up the ODL with mininet using the latest version of ODL which I downloaded from their site. It seems that they have removed support for DELUX but I am using NextUI for it. But I am not able to install the feature odl-l2switch-switch or the odl-l2switch-switch-ui. It seems to be no longer available. Is there any other way to enable the reactive flow discovery feature in the ODL. I have been trying to find a solution for a while now.
opendaylight-user@root>feature:install odl-l2switch-switch
Error executing command: No matching features for odl-l2switch-switch/0.0.0
opendaylight-user@root>feature:list |grep l2switch
I was not able to get a reactive flow entry after connecting to the controller.

The flow table in the ovs switch seems to be empty.

I have installed the features that looks like they are responsible for this, without any success.

please point me in the right direction. All the online questions and answers seems to be aimed at the earlier versions of the ODL Controller. This being a highly used controller, there should be a way to achive this.
