Abstract          

   This document specifies Fault Management solution for network
   virtualization overlay networks. Methods in this document follow the
   IEEE 802.1 CFM framework and reuse OAM tools where possible.
   Additional messages and TLVs are defined for IETF overlay OAM
   specific applications or where extensions beyond IEEE 802.1 CFM are
   required.
