BFD

Working Group Status. BFD Wiki

Not meeting in Buenos Aires

New RFCs:

  • RFC 7726 - Clarifying Procedures for Establishing BFD Sessions for MPLS Label Switched Paths (LSPs)

Existing Work:

Multipoint work stable, getting implementations for base spec. Trill has dependency on active head case. Technically ready for WGLC, but no consensus to move forward last IETF-94.

S(eamless)-BFD documents all working their way through the IESG queue.

BFD MPLS MIB stalled.

Crypto:

  • Generic keying mehanism stalled.
  • SHA-1 similarly stalled.
  • New work on optimizing authentication - some progress, needs discussion with security area.

BFD Yang, no progress since last IETF.

Potential new work:

Work on BFD outside of Working Group:

Links: Agenda WG Charter Raw Notes

I2RS

  • I2RS is a "re-use" protocol where the goal is to re-use and extend a protocol rather than create new one.
  • This process takes a different path: define the problem, the new architecture, the potential "re-use" protocols, the requirements for extension, the security for the protocol the security environment, and the protocol "strawman" that describes how the "new protocol" comes from the old protocol. This mechanism means that we do not "re-invent" the protocols, and hopefully speed things to market.
  • One challenge/benefit with this process is it takes a great deal cooperation/flexibility between "old protocol" and "new protocol" developers.
  • The second challenge is that the process of finalizing the work requires a lot of "double-checking" to make sure all the necessary changes.
  • In 2015, we finalized the general scope of the problem, architecture, two potential "re-use" protocol (NETCONF/RESTCONF), the extensions, the security, and the security environment, a protocol strawman, and our base yang modules.
  • IETF 95 focused on checking to see if we needed another "re-use protocol", checking to see if the all the requirements and protocol strawman are ready to go to netconf or netmod.
  • netmod/restconf chairs/experts + security have been very helpful and cooperative.
  • At the same time, the IETF hackathon had two projects (NETCONF push) and the I2RS RIB Yang model project that made significant progress in getting an open source project up and working.
