As Alvaro suggested, we could have incorporated all of RFC8113 here, and obsolete it. But it also is ok as a standalone. The group wanted to continue with it as a standalone. I think though we need to be clear on the relationships. I think Dino is right, RFC8113 is only (and should be only) informative here. There are some inter-relationships which we should clarify in this document and 8113bis. Also need to clarify a bit more what is to be done in the IANA section - I'm sure IANA will do ok - but it will make it clearer for others.

(Thanks Alvaro!!!)

Section 5.1
=========
OLD
For completeness, this document references the LISP Shared Extension Message assigned by [RFC8113].
NEW
For completeness, the summary below includes the LISP Shared Extension Message assigned by [RFC8113].
OLD
Values in the "Not Assigned" range can be assigned according to procedures in [RFC8126].  Documents that request for a new LISP packet type may indicate a preferred value.
NEW
Values in the "Not Assigned" range can be assigned according to procedures in [RFC8113].
(Deborah: 8113 set up the guidelines for the unassigned, the reader should refer to it. This will answer Alvaro's question on the procedures. Hint for Alvaro: unassigned is done via standards action.)
OLD
Protocol designers experimenting with new message formats SHOULD use the LISP Shared Extension Message Type and request a [RFC8113] sub-type assignment.
NEW
Protocol designers experimenting with new message formats are recommended to use the LISP Shared Extension Message Type [RFC8113].
(Deborah: I think this sentence could be deleted, but if want to keep, I think it should not be "normative")

LISP Packet Type Codes
===================
* For authors of RFC8113bis: need to add to 8113bis "updates 6833bis"
Suggest:
OLD
It is being requested that the IANA be authoritative for LISP Packet Type definitions and that it refers to this document as well as [RFC8113] as references.
New
It is being requested that the IANA be authoritative for LISP Packet Type definitions and it is requested to replace the [RFC6830] registry message references with the RFC number assigned to this document.

OLD
message type 5, was added to this document NEW message type 5,
NEW
message type 5, was added by this document NEW message type 5,

LISP ACT and Flag Fields
====================
OLD
Four values have already been allocated by [RFC6830].  
NEW
Four values have already been allocated by [RFC6830], IANA is requested to replace the [RFC6830] reference for this registry with the RFC number assigned to this document and the [RFC6830] Action values references with the RFC number assigned to this document.

That is not the part I had a problem with. Consider it added.
