Yours,

Dear WG:
We have just posted
https://www.ietf.org/internet-drafts/draft-ietf-6man-spring-srv6-oam-05.txt.
This version addresses comments received during the interim meeting and
all outstanding comments.
Since the interim meeting:
* The authors had WebEx calls with Joel M. Halpern and Bob Hinden.
* The authors also had a WebEx with Greg Mirsky.
* During these calls, the author went over their comments and walked
over how the proposed diffs address their feedback.
The authors thank Joel, Greg, Loa, Bob and the WG for all the comments.
The authors believe that the diffs address their and other outstanding
comments from the WG.
How the diffs address the comments is detailed in the following:
* Joel Halpern comment from the interim meeting,
https://datatracker.ietf.org/doc/minutes-interim-2020-6man-01-202003310730/.
Specifically, "Joel Halpern: You said you added illustrations to
address my comments. You did add illustrations, but the description
does not address my comment. The document needs to address what the
router actually has to do when the O bit is set. The text does not
describe this."
o Section 2.1.1. O-flag Processing has been enhanced to address
Joel's comments. It has been reviewed with Joel and Bob during
the WebEx meeting with them. The author believes the changes
address Joel's comments.
* Greg Mirsky's comment from the interim meeting,
https://datatracker.ietf.org/doc/minutes-interim-2020-6man-01-202003310730/.
Specifically, "Greg Mirsky: I did not read the latest version, so I
haven't seen the latest changes. I think your interpretation of RFC
7799 is incorrect. O-bit, according to the definition or active,
passive, and "in-between." OAM would be an example of the hybrid OAM
method. I also think what you are trying to achieve with O-bit is
achievable with current iOAM (in-situ OAM). "
o The terminology now uses the hybrid OAM mechanism. Section
2.1.1. (O-flag Processing) Section 3.3 (A Controller-Based
Hybrid OAM Using O-flag) has been enhanced to address Greg's
comments. The diffs have been discussed with Greg during the
WebEx meeting with them. The author believes the changes address
Greg's comments.
* There was an outstanding comment from Greg in
https://mailarchive.ietf.org/arch/msg/ipv6/esi3EWdjWMEu9zSP-pjzxI2gEmw/.
Specifically, Greg asked: Isn't using assigned by IANA port number
sufficient to identify active IP OAM packets? Wouldn't the same be
applicable in SRv6 OAM? Removed END.OP SID and the associated
changes in the illustration section to address this comment.
* The new version addresses pending comments from Loa Anderson by a
rewrite of the introduction and abstract. All other comments from
https://mailarchive.ietf.org/arch/msg/ipv6/LKsWbnA0aWYem4AbHWrUURNd-3c/ has
been already addressed.
* Migrated addresses used for illustration to IPv6 addresses reserved
for documentation.
* Fixed .xml file, as per Bob’s comment.
* Fixed IDnit issues.
* Misc. editorial changes including illustration enhancement in 3.4
(Monitoring of SRv6 Paths)
Thanks
