BFD

As always, current status of WG in the BFD Wiki

Current items of interest:

  • BFD multipoint documents in extended WGLC. Received some feedback, awaiting some additional commentary from implementors.
  • BFD Yang module revised. Issues with interworking with IGP modules. Likely to cause short virtual interim after IETF 99 if mail list discussion doesn't resolve.
  • BFD directed document in the MPLS working group still has some controversy. Impact on BFD if the work continues may require a RFC 5884 update.
  • Two BFD related documents being presented in MPLS WG on Friday:

PALS

Meeting Day/Time: Monday, July 17, 17:40-18:40

WG Highlights:

  • PALS met for the first time since IETF 95.
  • The primary focus of the WG is draft-bryant-pals-ethernet-cw, which mandates the use of the Control Word for Ethernet pseudowires (PWs) if both endpoint routers support the Control Word. This is to prevent reordering problems that result from some core routers mistakenly applying ECMP to Ethernet PWs if they look below the MPLS header and see a first nibble of 0x4 or 0x6 in the Ethernet MAC address, and they mistake these packets for IPv4 or IPv6. This problem has been observed in the field. Use of the control word will prevent ECMP from being applied. As both WG co-chairs are co-authors of the draft, Matthew Bocci (former PWE3 co-chair) has agreed to shepherd and run the process. Once it's been adopted, PALS plans to liaise to our IETF partners (e.g., BBF, ITU-T SG15, IEEE 802.1&.3) to let them know about the work so they can plan appropriate action. We hope to complete the draft by IETF 100.
  • A proposal for a PW YANG data model was presented. The authors are going to work with the authors of the YANG Data Model for MPLS-based L2VPNs in the BESS WG to merge their work.

WG Status Summary:

  • Two new RFCs since IETF 98.
    • WG has published 14 RFCs since November 2015.
  • Two drafts in the RFC Editor's queue.
  • Two drafts in IESG review and processing.
