I've setup a single core node with several compute nodes all running RDO Icehouse with Neutron. I have two public networks with floating ip's, bridged into their respective flat neworks, all hosted out of the core node. All of it is working except whenever I associate/disassociate a floating-ip with an instance, the change does not take affect until I restart the relevent l3-agent. Why is the l3-agent not getting notified automatically of the change?
