Dear Marcus, alt-mark-deployment authors, IPPM and BMWG,

I read the document, it is well-written and I support its publication. =
Here some comments:

- The abstract says =E2=80=9Cincludes considerations and guidance=E2=80=9D=
. I feel that =E2=80=9Cconsiderations" are covered, while "guidance=E2=80=9D=
 we could have a bit more text around.=20
For example, end of section 2, it states that the controlled domain =
could be including the (1) CPE or the (2) PE. One could ask which =
parameters (singled-marked vs doubled-marked, which period is better, =
etc=E2=80=A6) a user SHOULD deploy in an environment including the CPE =
and which parameters SHOULD be used on one that only covers the PE. Are =
they different? Are they not? I was expecting some text around those =
lines.

- In Section 6, 7 and 8, we have references to other documents, this is =
very welcomed. However, there are some references that are expired:
- (1) I-D.ietf-ippm-alt-mark-yang, this one is in WGLC, good (my =
comments here: =
https://mailarchive.ietf.org/arch/msg/ippm/G_YsERqR4C5GZWyHPZBKarr2Evs/)
- (2) [I-D.ietf-idr-sr-policy-ifit], =
[I-D.ietf-idr-bgp-ifit-capabilities], [I-D.ietf-pce-pcep-ifit]: these =
are adopted documents. I am not active at these WGs, but I assume they =
will become RFCs. By doing a search on the IDR and PCE agenda, they have =
not been discussed during the WG meeting for a few IETFs. Can the =
authors verify if they are still active? IETF meeting activity says =
otherwise.
- (3) The authors reference draft-fz-spring-srv6-alt-mark-17 in Section =
7. This is now RFC9947. Please update. Note also this one is Independent =
Submission rather than an IETF document.
- (4) I-D.ietf-opsawg-ipfix-alt-mark is in WGLC. Good
- (5) I-D.ietf-ippm-on-path-telemetry-yang is adopted and being =
discussed at IPPM. Good. (I will provide feedback at IPPM).=20
- (6) I-D.ietf-ippm-hybrid-two-step is at the IESG. Good.
- (7) I-D.wang-ippm-ipv6-flow-measurement and =
I-D.wang-ippm-ipv6-distributed-flow-measurement are individual =
documents. The second one is expired.
- (8) I-D.ietf-bier-pmmm-oam is adopted. Good.
- (9) I-D.cx-mpls-mna-inband-pm, I-D.mfm-ippm-sfc-nsh-pmamm and =
I-D.fmm-nvo3-pm-alt-mark are individual submissions. Some of them are =
expired.
- (10) I-D.zhou-ippm-enhanced-alternate-marking also individual still.

I think it is useful to have all these references, it provides a wide =
view of the applicability of AltMark. My only worry is the expired =
individual drafts, where the authors could abandon the document if not =
adopted. Please check with the other authors if some of the documents =
are not planned to become RFC anymore.

- Editorial:
s/YANG Push/YANG-Push/ (to align with terms from RFC8641)
s/periodical subscriptions/periodic subscriptions/ (to align with terms =
from RFC8641)
s/leafes/leafs/

- First sentence of Section 7.2 should reference RFC8641 instead of =
RFC8639:
OLD:
For YANG Push [RFC8639], =E2=80=A6
NEW:
For YANG-Push [RFC8641], ...

Regards,
Alex
