Any router which has a <b>single</b> floating IP associated with one of its VMs. If there is more than one VM with a floating IP on that router, this won’t reproduce.<br/> 2. Any NeutronPort deletion (could be a vm port, external gateway interface port or even a floating-ip neutron port – none of them even has to be in the router from #1)</p> <p>This will cause deletion of the floating-ip address from all routers which have a single floating IP mapped to one of their VMs.</p> <p>The bug is in:<br/> dissociatefixedIPFromFloatingIP in NeutronFloatingToFixedIpMappingChangeListener.java<br/> In case a router is found with “portsList.size() == 1”, its routerPorts entry is deleted without any check whether this was the neutron port that was actually deleted..</p> <p>Fixed in <a href="https://git.opendaylight.org/gerrit/#/c/46985/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/46985/</a></p> Development External issue ID 6824 External issue URL Rank 0|i01q67:
