DISCUSS:

** Section 2.

   If a BAR value is not specified in a RFC but only privately used for
   a deployment, it MUST be within the "240-254 Experimental Use" range
   of the registry.

If this document is redefining “experimental use” to be “privately used for a deployment” please provide the appropriate applicability statement that bounds this “deployment”.

Zzh> The intention is that if a deployment uses a BAR value that is not covered in a specification, then it must be from that range. Based on the suggestions I've updated the text as the following:

    If a specification is not available for a specific BAR, its 
    value MUST be from the Private or Experimental Use range of 
    the registry.

Thank you to Vincent Roca for the SECDIR review.

** Section 2.  I support Paul Wouter’s DISCUSS on his concerns on:

   If a BAR value is not specified in a RFC but only privately used for
   a deployment, it MUST be within the "240-254 Experimental Use" range
   of the registry.

This text suggests that BAR values will be either published in an RFC or NOT.
The current ranges in that IANA registry (https://urldefense.com/v3/__https://www.iana.org/assignments/bier/bier.xhtml*bier-algorithm__;Iw!!NEt6yMaO-gk!U2KKSOJNf6MUTSOAxpFfuY4UsnsdVEYq9h-pZlVjGtJ_XvgyJtSTfAjnJ_WxfsG1$ ) suggest that that only 0-127 is an RFC (Standards Action), but 128 – 239 could be either RFC or other specification (Specification Required).

Zzh> Please see the above new text.

** Section 2.

The definition for the BAR and IPA fields in [RFC8401] and [RFC8444]
   are updated as follows.

 Please be specific on which text is being modified – Section 6.1 of RFC8401  and Section 2.1 of RFC8444.

Zzh> Yes it will be fixed in the new revision.
Zzh> Thanks!
