I miss the DISCUSS point here, and there is not section 2.2 (may be a cut and paste error?)

At the very very beginning there were a couple of options on where to place the version number in the header (original suggestion was in replacement of the Loc-Status-Bits). So, we described the general algorithm without specifying the real size of the field.

The MUST NOT is actually part of the overall review and discussion that has been held about 6830bis and 6833bis (and 6834bis).
Consensus was on the MUST NOT be used. We can actually merge the sentence with the previous paragraph to highlight the link with those documents:
  
   This document builds on the specification and operation of the LISP
   control and data planes.  The Security Considerations of
   [I-D.ietf-lisp-rfc6830bis <https://datatracker.ietf.org/doc/html/draft-ietf-lisp-6834bis#ref-I-D.ietf-lisp-rfc6830bis>] and [I-D.ietf-lisp-rfc6833bis <https://datatracker.ietf.org/doc/html/draft-ietf-lisp-6834bis#ref-I-D.ietf-lisp-rfc6833bis>] apply, as such 
   Map-Versioning MUST NOT be used over the public Internet and SHOULD
   only be used in trusted and closed deployments.  A
   thorough security analysis of LISP is documented in [RFC7835 <https://datatracker.ietf.org/doc/html/rfc7835>].


Would this work better?

Thanks. Will fix as suggested.

Thank you again for the review.

Ciao
