    abstract =  {This document describes extending Virtual eXtensible Local Area Network (VXLAN), via changes to the VXLAN header, with four new capabilities: support for multi-protocol encapsulation, support for operations, administration and maintenance (OAM) signaling, support for ingress-replicated BUM Traffic (i.e. Broadcast, Unknown unicast, or Multicast), and explicit versioning. New protocol capabilities can be introduced via shim headers.},
