            EVPN Operations, Administration and Maintenance
                       Requirements and Framework
                 draft-salam-bess-evpn-oam-req-frmwk-00

Abstract

   This document specifies the requirements and reference framework for
   Ethernet VPN (EVPN) Operations, Administration and Maintenance (OAM).
   The requirements cover the OAM aspects of EVPN and PBB-EVPN.  The
   framework defines the layered OAM model encompassing the EVPN service
   layer, network layer and underlying Packet Switched Network (PSN)
   transport layer.
