Hi all,
I wonder what are the WG plans (if any) regarding YANG data models for MPLS-TP.

While it is obviously true that static MPLS and MPLS-TP are different (neither is the subset of the other), MPLS-TP is today the most important application of static MPLS.

However, after looking up  draft-ietf-mpls-static-yang<https://datatracker.ietf.org/doc/draft-ietf-mpls-static-yang/?include_text=1> I did not find there any mention of MPLS-TP-specific issues.

One example that comes to mind is co-routed bi-directional and associated bi-directional MPLS-TP LSPs. Other issues include:

1.       MPLS-TP Identifiers (i.e. YANG model for RFC 6370<https://tools.ietf.org/html/rfc6370>)0>). From my POV such a data model is a pre-requisite for all MPLS-TP-related work

2.       MPLS-TP protection mechanisms

3.       MPLS-TP OAM mechanisms. There is an individual draft<https://datatracker.ietf.org/doc/draft-zhang-mpls-tp-yang-oam/?include_text=1> that tries to address these issues, but it looks to me like very much incomplete. E.g.:

o   It does not even mention RFC 6428<https://tools.ietf.org/html/rfc6428>

o   While RFC 6427<https://tools.ietf.org/html/rfc6427> appears in the list of Normative references in this draft, there are no actual references to this document.

Any inputs in this regard would be highly appreciated.

Regards, and lots of thanks in advance,
Sasha
