  2. Based on MPLS OAM and Customer Requirements • Driven by a need to provide a common set of OAM mappings from PWE3 transport networks to native OAM types. • ftp://ftp-eng.cisco.com/tnadeau/oam/draft-nadeau-mpls-oam-requirements-00.txt • Soon to be draft-ietf-mpls-oam-requirements-00.txt • Existing PW3 encapsulation drafts were spotty in their specification of OAM: • Some skipped this and some did not. • Inconsistent for implementations.

  3. Overview • Provides details of how LSP ping/VCCV failures should translate into native ATM/FR OAM messages that PEs return to the native attachment interfaces. • OAM Emulation • AIS and RDI Generation for ATM AAL5 over MPLS • AIS/RDI Generation for ATM upon reception of label withdrawal and vice versa • LMI/ILMI based status notification upon label withdrawal reception for AToM VCs • LC-ATM/XTAG Interface status notification using OAM cells

  5. Open Issues • Ethernet encapsulation OAM left as TBD. • Possible draft name change.

  6. Next Steps • Refinements • Editorial enhancements. • Accept as a PWE3 WG document to keep as a central point of OAM definition for PWE encapsulations.

  7. Thank You
