   Procedure to handle host mobility in a layer 2 Network with EVPN
   control plane is defined as part of RFC 7432. EVPN has since evolved
   to find wider applicability across various IRB use cases that include
   distributing both MAC and IP reachability via a common EVPN control
   plane. MAC Mobility procedures defined in RFC 7432 are extensible to
   IRB use cases if a fixed 1:1 mapping between VM IP and MAC is assumed
   across VM moves. Generic mobility support for IP and MAC that allows
   these bindings to change across moves is required to support a
   broader set of EVPN IRB use cases, and requires further
   consideration. EVPN all-active multi-homing further introduces
   scenarios that require additional consideration from mobility
   perspective. This document enumerates a set of design considerations
   applicable to mobility across these EVPN IRB use cases and defines
   generic sequence number assignment procedures to address these IRB
   use cases.
