    Abstract: Techniques for communication network routing include receiving, at a routing device associated with a first site in an overlay communication network, a dynamic parameter value associated with each of a plurality of additional sites in the overlay communication network. The plurality of additional sites are each configured to provide a first network service for a computing device in the first site. A second site in the overlay communication network is selected, from among the plurality of additional sites, based on a first dynamic parameter value associated with the first site and a received second dynamic parameter value associated with the second site. The first network service is provided from the second site for the computing device, based on the selecting the second site.

    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.
