Hi Alvaro,

thanks for the reply. I think everything is clear. I need just one clarification:

I think I’ve got now you point. What we should do is not modify section 5.1, is modifying section 11.2.
We should update the text and following table:
	Name                 Number          Defined in
        ----                 ------          -----------
        LISP Map-Notify-Ack  5               RFC6833bis


We should add there all the code points of messages that are re-defined in this document and ask IANA to update the registry so that the entries point to this document (and not anymore 6830).

Did I got it right?

Ciao
