Hi Aijun,

Thanks for the quick turnaround.

I didn’t have time to do a full review but I notice you appear to have done a 
global search-and-replace of “should” with “SHOULD”. This has led to a new 
problem; Roman dropped his old DISCUSS (thanks for that) but entered a new one 
based on the new use of SHOULD.

I imagine a review comment triggered the global replacement. I haven’t found 
the comment, however I doubt the ask was to do a global replacement! I suggest 
reverting the global change, which would (I believe) fix Roman’s new DISCUSS. 
Then we can consider if there is a need for other should/SHOULD changes on a 
case-by-case basis. If you agree to revert the should/SHOULD change, I 
encourage you to publish the new version right away; I would rather review the 
34->36 diff than the rather noisy 34->35 diff.

On a related topic, Zahed’s COMMENT asks about two SHOULD clauses in the 34 
version (i.e. they are not affected by the global change). I’m not sure what 
your answer is, but I suggest changing those two to MUST unless you think there 
is some reason not to (in which case please help us understand).

Thanks!

—John

Hi, Roman, John and Dhruv:

I have updated the document according to your following suggestions:
1)     Add the normative reference to draft-ietf-pce-iana-update, as John 
suggested.  Wish we can forward “draft-ietf-pce-iana-update” in fast track.
2)     Add the suggested descriptions from Dhruv for the “Experimental Status”  
of this document as one new subsection “section 2.2 Experimental Status 
Consideration”

I will upload the updated document later, together with other expert’s review.
Thanks all your efforts for the suggestions!

** Section 14.2.

14.2.  PCECC-CAPABILITY sub-TLV's Flag field

   [RFC9050] created a sub-registry within the "Path Computation Element
   Protocol (PCEP) Numbers" registry to manage the value of the PCECC-
   CAPABILITY sub-TLV's 32-bit Flag field.  IANA is requested to
   allocate a new bit position within this registry, as follows:

The registration policy of PCECC-CAPABILITY sub-TLV
(https://www.iana.org/assignments/pcep/pcep.xhtml#pcecc-capability<https://urldefense.com/v3/__https:/www.iana.org/assignments/pcep/pcep.xhtml*pcecc-capability__;Iw!!NEt6yMaO-gk!B5PLFQZKBPmXYlwyMLc8dKsZAHy4c44OJGkxvAvngU6q_uyvvDK6tLmHr5iCB7dAiMekXL_kprM$>)
 is
“Standards Action”.  This document has experimental status and does not qualify
for registration.

Dhruv: We have a document in the PCE WG to fix it -  
https://datatracker.ietf.org/doc/draft-ietf-pce-iana-update/<https://urldefense.com/v3/__https:/datatracker.ietf.org/doc/draft-ietf-pce-iana-update/__;!!NEt6yMaO-gk!B5PLFQZKBPmXYlwyMLc8dKsZAHy4c44OJGkxvAvngU6q_uyvvDK6tLmHr5iCB7dAiMekFueWoGw$>
The document is being fast tracked by the WG.

Note that this code point has already been allocated through the temporary 
allocation process and doesn’t expire until 2025-08-14. I anticipate that 
draft-ietf-pce-iana-update will have been progressed well before then, at which 
point the code point can be made permanent.

It subsequently occurred to me that if draft-ietf-pce-pcep-extension-native-ip 
adds a normative reference to draft-ietf-pce-iana-update then we should be all 
set — draft-ietf-pce-pcep-extension-native-ip can enter the RFC Editor's queue 
and they can start work on it, but those concerned about the registration 
policy issue can rest assured that it won’t be issued as an RFC until 
draft-ietf-pce-iana-update is also published (it’ll be a cluster, because of 
the normative ref). Q.E.D., the problem will be resolved by or before the time 
the RFC is issued.

Work for everyone?

[Roman] Yes.  That works for me.

Roman
