You may review the report below and at:

--------------------------------------
Status: Held for Document Update
Type: Technical

Reported by: Kris Lambrechts <[email-masked]>
Date Reported: 2022-02-10
Held by: Alvaro Retana (IESG)

Section: 7.2. grouping prefix

Original Text
-------------
       leaf mask-length-upper {
         type uint8 {
           range "1..128";
         }

Corrected Text
--------------
       leaf mask-length-upper {
         type uint8 {
           range "0..128";
         }

Notes
-----
With the original definition, it is not possible to specify an exact match for the default routes (0.0.0.0/0 and ::/0) which is a valid use case.

=====  AD Note ====
This report is valid, but the resolution requires an update to the YANG model and not just a text correction.
