Subject: [AD] Re: AUTH48: RFC-to-be 9862 
<draft-ietf-pce-segment-routing-policy-cp-27> for your review

Hi Samuel and *Roman,

* Roman - As AD, please review the following changes in Sections 4.4, 6.5, and 
6.6 and let us know if you approve. The updates can be viewed here: 
https://www.rfc-editor.org/authors/rfc9862-auth48diff.html.

a) Section 4.4 (addition of “shortest” below):

OLD:

 An example use case is to terminate the SR Policy before reaching the  
Endpoint and have decapsulated traffic be forwarded the rest of the  path to 
the Endpoint node using the native Interior Gateway Protocol
 (IGP) path(s).

NEW:

 An example use case is to terminate the SR Policy before reaching the  
Endpoint and have decapsulated traffic be forwarded the rest of the  path to 
the Endpoint node using the Interior Gateway Protocol (IGP)  shortest path(s).

b) Sections 6.5 and 6.6 (updates to the definitions in the IANA Considerations 
section):

OLD:

 D: dropping - the LSP is currently attracting traffic and actively dropping it.

 D: drop enabled - the Drop-upon-invalid is enabled on the LSP.

NEW:

 D: Dropping - the LSP is actively dropping traffic as a result of 
Drop-Upon-Invalid behavior being activated.

 D: Drop enabled - the Candidate Path has Drop-Upon-Invalid feature enabled.


Samuel - Thank you for your reply; we have updated the document accordingly.

A few follow-up notes:

We have left the text in Section 5.2.3 as is and have updated these definitions 
in the IANA Considerations section (Sections 6.5 and 6.6) to match how they 
appear in Section 5.2.3. Note that we will ask IANA to make this update along 
with the other registry updates.

We have updated the items above accordingly. Please note that we have also 
updated the terms below (all from Section 5.2.2.) as follows. Please review and 
let us know if these updates are suitable:

OLD:

Explicit NULL Label [RFC3032]
Explicit NULL label
Explicit Null is currently only defined for… explicit null label

NEW:

Explicit NULL label [RFC3032]
Explicit NULL label
Explicit NULL is currently only defined for… Explicit NULL label

> Planning your review
> ---------------------
>
> Please review the following aspects of your document:
>
> *  RFC Editor questions
>
>    Please review and resolve any questions raised by the RFC Editor

>    coauthors.  We assume that if you do not speak up that you
>    agree to changes submitted by your coauthors.
>
> *  Content
>
>    Please review the full content of the document, as this cannot

>
> *  Formatted output
>
>    Please review the PDF, HTML, and TXT files to ensure that the
