Clustering : A 3-Node cluster is not stable when connecting mininet to the inventory Leader node

But I really would like to run this with 3 real controllers before I close this. Let's keep it open for now.</p> <p>Tested with real cluster - seems to be stable. Will open more specific bugs as needed.</p> <p>Here are all the related commits,</p> <p><a href="https://git.opendaylight.org/gerrit/#/q/message:2676" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/q/message:2676</a></p> Development External issue ID 2676 External issue URL Issue Type ODL SR Target Milestone Priority Rank 0|i02opr:
