draft-ietf-bess-evpn-oam-req-frmwk-01
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.
