Overview

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


Status update

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


Next steps

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

PWE3

  • OAM Interworking possible to utilize OAM across Layers

  • However, each layer must support OAM capabilities independently


Status update1

Status Update

  • IETF-62 (Minneapolis – current meeting)

    • draft-ietf-l2vpn-oam-req-frmk-02.txt update submitted

      • Editorial updates based on discussion during IETF-61 meeting

  • IETF-61 (Washington D.C.)

    • draft-ietf-l2vpn-oam-req-frmk-01.txt discussed

    • Agreement to continue work for L2VPN Service OAM

    • Agreement to specifically identify requirements on underlying technologies supporting L2VPN e.g. PWs and/or LSPs

  • IETF-60 (San Diego)

    • Draft-ietf-l2vpn-oam-req-frmk-00.txt submitted

    • Overwhelming support for draft-mohan-sajassi-oam-req-frmk-00.txt to progress as a WG draft (during IETF-59 Seoul meeting and mailing list)
