                  Generic Protocol Extension for VXLAN
                    draft-ietf-nvo3-vxlan-gpe-01.txt

Abstract

   This draft describes extending Virtual eXtensible Local Area Network
   (VXLAN), via changes to the VXLAN header, with three new
   capabilities: support for multi-protocol encapsulation, operations,
   administration and management (OAM) signaling and explicit
   versioning.
