Abstract
This disclosure describes techniques and mechanisms to enable proactive convergence of endpoints in a network corresponding to virtual machine mobility scenarios. The techniques may be used individually or together to reduce convergence times and improve network security. The techniques may include proactively exchanging IP-MAC binding information between an old location and a new location of a virtual machine; (2) utilizing a route reflector and a convergence efficient flood order to update the location of the virtual machine at the old location to point to the new location; (3) proactively poisoning the route to the virtual machine at the old location; and (4) utilizing an orchestrator to proactively notify leaf(s) of reachability information of the virtual machine prior to or during migration of the virtual machine.
