Hi Med,
Thanks for your comments.
I visited IANA in Philly to validate this propose, but we could
re-evaluate & discuss about it.
We need a registry because just telling that we take the value from
https://www.iana.org/assignments/ipv6-parameters/ipv6-parameters.xhtml#segment-routing-header-flags
is not sufficient as we also need to specify the following IPFIX fields:
- Abstract Data Type. (unsigned8 in this srhFlagsIPv6 case)
- Data Type Semantics (flags in srhFlagsIPv6 case)
Now, if your point is that we don't really to mention the initial values ...
Initial values in the registry are defined by the table
below.
+--------+-------------------+--------------------------------------+
| Value | Description | Reference |
+--------+-------------------+--------------------------------------+
| 0-1 | Unassigned | |
+--------+-------------------+--------------------------------------+
| 2 | O-flag |
[RFC-ietf-6man-spring-srv6-oam-13] |
+--------+-------------------+--------------------------------------+
| 3-7 | Unassigned | |
+--------+-------------------+--------------------------------------+
Table 2: "IPFIX IPv6 SRH Flags" registry
... I agree it's not strictly necessary but it helps (me/the IPFIX
experts) to understand, from this document, which type of values are
currently available.
See inline.

Hi Thomas,
Thank you for preparing this revised version.
I think almost all my comments are addressed in this version. However,
I still don’t see the need to have new registries that only mirror
existing ones. For example, and unless I missed some subtleties, it
would be sufficient to say that the flag values are taken from
https://www.iana.org/assignments/ipv6-parameters/ipv6-parameters.xhtml#segment-routing-header-flags
<https://www.iana.org/assignments/ipv6-parameters/ipv6-parameters.xhtml#segment-routing-header-flags>rather
than adding the following in the I-D:
+--------+-------------------+--------------------------------------+
| Value | Description | Reference |
+--------+-------------------+--------------------------------------+
| 0-1 | Unassigned | |
+--------+-------------------+--------------------------------------+
| 2 | O-flag | [RFC-ietf-6man-spring-srv6-oam-13] |
+--------+-------------------+--------------------------------------+
| 3-7 | Unassigned | |
+--------+-------------------+--------------------------------------+
Table 2: "IPFIX IPv6 SRH Flags" registry
which is similar in term of encoding and values as what was set by
RFC9256:
IANA has registered the following in the "Segment Routing Header
Flags" subregistry in the "Internet Protocol Version 6 (IPv6)
Parameters" registry:
+=====+=============+===========+
| Bit | Description | Reference |
+=====+=============+===========+
| 2 | O-flag |RFC 9259
<https://datatracker.ietf.org/doc/html/rfc9259> |
+-----+-------------+-----------+
BTW, I guess you initially meant:
NEW:
Table 2: "IPFIX IPv6 SRH Flags" registry
Note to IANA: Add a note to the "Segment Routing Header Flags"
registry
so that new values are echoed in the new "IPFIX IPv6 SRH Flags”
You are right (since
https://www.iana.org/assignments/ipv6-parameters/ipv6-parameters.xhtml#segment-routing-header-flags
is "IETF review" while
https://www.iana.org/assignments/ipfix/ipfix.xhtml is "Expert Review")
instead of CURRENT:
Table 2: "IPFIX IPv6 SRH Flags" registry
Note to IANA: Add a note to the registry so that new values are
echoed in the new "IPFIX SRv6 EndPoint Behavior
The same comment applies for the values that can be directly taken
from
https://www.iana.org/assignments/segment-routing/segment-routing.xhtml#srv6-endpoint-behaviors.
Yes
OLD:
Table 4: "IPFIX SRV6 Endpoint Behavior" registry
Note to IANA: Add a note to the registry so that new values are
echoed in the new "IPFIX SRv6 EndPoint Behavior
NEW:
Table 4: "IPFIX SRV6 Endpoint Behavior" registry
Note to IANA: Add a note to the "IPFIX SRV6 Endpoint Behavior"
registry so that new values are
echoed in the new "IPFIX SRv6 EndPoint Behavior

Dear Med,
Many thanks for the comprehensive review. Much appreciated. We merged
all your input to the upcoming -01 release.
https://raw.githubusercontent.com/graf3net/draft-tgraf-opsawg-ipfix-srv6-srh/main/draft-ietf-opsawg-ipfix-srv6-srh-01.txt

For some we need further clarifications if we addressed them
correctly. I would appreciate if you could clarify the following three
points:
Med> Section 2, remark: "Why do we need three IE,
srhSegmentIPv6ListSection, srhSegmentIPv6BasicList and srhSectionIPv6,
to expose SRH Segment List
Thomas> Section 5.1 should provide the answer. If that should not be
sufficient, please suggest how this could be better expressed.
Med> Section 2: remark: "as series of n octets" is not clearly
comprehensible.
Thomas> Extended to "as series of n octets in IPFIX". Does that makes
it clearer?
Med> Section 4.11, remark: "Do you really need to define a new
registry here?"
Thomas> The registry could potentially be used (and updated) by non
IPFIX people.
Best wishes
Thomas

Hello, WG. We’d like to begin a two week call for adoption of this
work. Even as an individual draft it has already received some
reviews and has iterated quite a bit. Based on IETF 114 there does
seem to be interest in adopting this in opsawg, but we need a formal
adoption poll.
Please review and provide your adoption thoughts no later than
September 1, 2022.
Thanks.
Joe
