Stephane,
Lots of thanks for a prompt response.
I think that a proposal to extract FRR-related things from the IGP YANG data
models and to move them to a new document in a different WG would be rejected
at this stage - and justly so.
On the other hand, I wonder what is supposed to happen with YANG for TI-LFA:
- I would expect substantial overlap with YANG definitions for
LFA-based FRR in IS-IS and OSPF
- Since these definitions are in two different documents handled by
the LSR WG, and TI-LFA is handled by the RTGWG, this would probably mean yet
another draft, with its own lifecycle etc.
Keeping all these documents consistent (at least in their overlapping parts)
can be quite non-trivial IMHO.
One practical (and easy to implement) step should be removal of the milestone
"Submit MIB for IP Fast-Reroute for publication as Proposed Standard" (with the
target date two years behind us already) from the RTGWG
charter<https://datatracker.ietf.org/group/rtgwg/about/>. Chris/Jeff?

That's a possibility. However for now, we have taken the approach to add FRR
into the IGP models.
You could propose your view to the LSR list. ISIS and OSPF yang are in
Shepherd's review state.

Stephane,
Lots of thanks for a prompt response.
I have guessed that the reason for dropping the MIB draft for IP FRR was
transition to YANG data models.
And it seems that the current versions of the OSPF and IS-IS Yang data model
drafts cover not just FRR-related counters but also FRR-related configuration
and state attributes.
However, this looks as duplicated definitions (with some protocol-specific
variations). Doesn't it make more sense to place all these definitions into a
single document?
Regards, and lots of thanks in advance,
Sasha

Hi Sasha,
It was decided to stop the work on this document and focus on YANG. The IPFRR
MIB counters are part of the OSPF and ISIS yang models.
Brgds,

Dear colleagues,
I have noticed that IP FRR MIB draft (that appears as one of the WG milestones
with November-2015 as the target date) has expired more than 2 years ago. At
the same time I have not seen any YANG draft that could be considered as its
replacement.
I wonder if there are any plans to resuscitate this draft or to replace it by a
YANG one.
Your timely feedback would be highly appreciated.
Regards, and lots of thanks in advance,
Sasha
