Layer 2 Virtual Private Network (L2VPN)
Operations, Administration, and Maintenance (OAM)
Requirements and Framework
Abstract
This document provides framework and requirements for Layer 2 Virtual
Private Network (L2VPN) Operations, Administration, and Maintenance
(OAM). The OAM framework is intended to provide OAM layering across
L2VPN services, pseudowires (PWs), and Packet Switched Network (PSN)
tunnels. This document is intended to identify OAM requirements for
L2VPN services, i.e., Virtual Private LAN Service (VPLS), Virtual
Private Wire Service (VPWS), and IP-only LAN Service (IPLS).
Furthermore, if L2VPN service OAM requirements impose specific
requirements on PW OAM and/or PSN OAM, those specific PW and/or PSN
OAM requirements are also identified.
