I have a topology composed by 12 switches controlled by OpenDaylight Lithium. I have installed only the feature odl-l2switch-switch-ui and the topology seen in the DLUX interface or obtained via rest is always incomplete: only a subset of links and switches are present in the topology. That not happens in Helium-SR4 where, installing the same feature above, the topology is correct and it shows every link and every switch. What could be the problem? Am I missing a special configuration in Lithium?
