Abstract: Methods and apparatus for optimizing data center routing in the event of virtual machine (VM) mobility are provided. In one embodiment, a first gateway router, acting as an interface between an Ethernet Virtual Private Network (EVPN) domain and a Locator/ID Separation Protocol (LISP) domain, detects EVPN mobility messages advertised when a VM that has moved connects to a gateway router at a data center. The first gateway router then initiates a LISP mobility event that registers the new location of the moved VM to a LISP mapping system. In another embodiment, the first gateway router may notify a second gateway router, located at another data center from which the VM departed, to clean up the state maintained in that data center. This notification may be made via EVPN or LISP mechanisms. In response, the second gateway router may insert a new sequence into the other data center.
