draft-ietf-l2vpn-oam-req-frmk-03.txt 2 Overview >L2VPN OAM Framework OAM Layering in context of L2VPN WG technologies L2VPN Service Layer, PW Layer, PSN Layer Customer, Service Provider, Network Operators roles OAM Constructs OAM Domains, MEPs and MIPs >L2VPN OAM Requirements Requirements for L2VPN Service OAM Expectation is that native technology OAM will be used (e.g. IEEE 802.1ag) Liaison activities are already taking place Requirements for underlying facilities OAM e.g. PW OAM

draft-ietf-l2vpn-oam-req-frmk-03.txt 3 Status Update >OAM framework is being adopted for other related work e.g. draft-delord-pwe3-oam-applications-01.txt >draft-ietf-l2vpn-oam-req-frmk-03.txt update submitted Section 7 added to discuss specific OAM requirements for L2VPN network layer e.g. PW OAM to support L2VPN Services VPWS OAM references draft-delord-pwe3-oam-applications-01.txt Duplication of information is intended to be avoided between two drafts. IPLS OAM is FFS

draft-ietf-l2vpn-oam-req-frmk-03.txt 4 Next Steps >Add VPWS OAM Requirements Depending on outcome from PWE3 discussions on draft-delord- pwe3-oam-applications-01.txt >Continue refining the requirements on PW OAM >Other editorial updates Update Acknowledgements (TBD) Simon Delord/Philippe Nigel - France Telecom Neil Harrison - British Telecom Lior Shabtay/Dan Cauchy - Atrica
