# Éric Vyncke, INT AD, comments for draft-ietf-mpls-msd-yang-10

Thank you for the work put into this document.

Please find below one blocking DISCUSS points (easy to address), some
non-blocking COMMENT points (but replies would be appreciated even if only for
my own education).

Special thanks to Tarek Saad for the shepherd's detailed write-up including the
WG consensus *BUT* it lacks the justification of the intended status.

I hope that this review helps to improve the document,

Regards,

-éric

# DISCUSS (blocking)

As noted in https://www.ietf.org/blog/handling-iesg-ballot-positions/, a
DISCUSS ballot is a request to have a discussion on the following topics:

## SRH content while the title is about MPLS

While not really a DISCUSS criteria, the title is only about MPLS while some
identities are about SRH, i.e., SR over an IPv6 dataplane => please remove MPLS
from the title or add SRH/SRv6 to the title.

I understand the catch 22 situation here but having 2 I-D would have been
cleaner, so, at least adapt the title and the abstract to mention SRH as well.
I also intend to clear this DISCUSS during the IESG telechat if the title is
not changed before.

# COMMENTS (non-blocking)

## Title

Suggest to remove all acronyms in the title as they are only adding confusion.

## Section 1

Even if "SID" is a well-known acronym per RFC editor, suggest to expand SID at
first use.

## Section 2.2

Unsure what is a "link on a node" ? Should it rather be "link attached to an
interface of a node" ?

## Section 4.1

Identities sometimes end with "srh" (e.g., "msd-base-srh") or start with "srh"
(e.g., "srh-max-end-pop"), suggest to be consistent and use "srh" always at the
beginning or at the end of the identities.

Avoid the nits issue by a leading text in this section mentioning RFC 9352 and
9088.

## Section 4.2

In `The MSD type is defined in IANA IGP MSD-Types registry.`, should it rather
be the YANG module of section 4.1 ?

## Section 5

Suggest using the order of section 4.1 then section 4.2 for the listed security
considerations.

## Normative references

Should the IANA registry for "IGP MSD-types" include the URI fragment ? I.e.,
https://www.iana.org/assignments/igp-parameters/igp-parameters.xhtml#igp-msd-types

Please remove RFC 2119 and 8174 as BCP 14 template is not used in this document.
