Re: [Teas] IANA managed modules for TE object types

Hi Tarek, all,

I fully agree with Adrian.

FWIW, we trying to have this be part of the YANG authors guidelines: see more details at:
https://datatracker.ietf.org/doc/draft-boucadair-netmod-iana-registries/

Cheers,
Med

Objet : [Teas] IANA managed modules for TE object types

Hi WG,

During the review of draft-ietf-teas-yang-te, Adrian raised an important point about IANA managing some YANG module that models specific TE types. For example, ID draft-ietf-teas-yang-te was modelling 'no-path' some error reasons as listed in https://www.iana.org/assignments/pcep/pcep.xhtml#no-path-vector-tlv or association types as defined in  https://www.iana.org/assignments/pcep/pcep.xhtml#association-type-field.

There are obvious advantages to having such YANG types in separate modules and letting IANA manage them. For example,

  1.  Other TE modules can freely import such types modules (without needing to import feature modules such as one defined in draft-ietf-teas-yang-te).
  2.  Allowing IANA to manage these modules may facilitate extensions in the future (IANA can automatically ensure that IANA types and YANG module are in sync).

The authors discussed this suggestion and would like to proceed with it, but want to make sure this is the recommended approach for other types that are managed by IANA and may be modelled in YANG in the future.

Regards,
Tarek (for the co-authors of draft-ietf-teas-yang-te)
