RE: A question on OAM section in draft-ietf-opsawg-l3sm-l3nm

[[e-mail]]

Hi Greg,

Thank you for checking the OAM part and for sharing this comment.

As you can read in both sections 4 and 5, this model is ** not a device configuration model **. The focus is on aspects that can be triggered by service requests and managed by the network controller. This network view of the service will be then enriched (with other sources such as local templates/profiles/defaults) to derive the exhaustive configuration that will be enforced in involved devices to deliver the requested service.

With that rationale in mind, you can understand why we don’t import device models but point to the authoritative RFCs for aspects that we think make sense to be tweaked at the network-level.

Thanks.

Cheers,
Med

Objet : A question on OAM section in draft-ietf-opsawg-l3sm-l3nm

Dear Authors,
thank you for your work on this document. I've read the draft and have a question, and a suggestion. Section 7.6.4<https://datatracker.ietf.org/doc/html/draft-ietf-opsawg-l3sm-l3nm#section-7.6.4> describes how BFD is controlled in vpn-common. I've noticed that you use references to RFC 5880. While that is the basis for all subsequent BFD documents, for BFD YANG data model draft-ietf-bfd-yang<https://datatracker.ietf.org/doc/draft-ietf-bfd-yang/> may be more useful. Perhaps the container oam can re-use grouping base-cfg-parms.
What are your thoughts?

Regards,
Greg
