Michael

Thank you for the quick reaction and the changes in the document. I am still in favor of a better phrasing for "that need addressing via unicast Router Solicitation messages", using a sentence around SLAAC would probably be more readable but this is up to you.

Regards and see you in your own country in a couple of weeks ;-)

    I have changed the Abstract to say "routers announce".
    Noting that in a 6tisch world, most things are routers.

    The name of the Registry is:
        https://www.iana.org/assignments/ieee-std-802.15.4-ietf-ie-subtype-ids/ieee-std-802.15.4-ietf-ie-subtype-ids.xhtml#ieee-std-802.15.4-ietf-ie-subtype-ids-1

    Yes, the point is to avoid multicast RS/RAs.
    If for reason, the announcing node is *not* a router, it should not set the R bit.
    Otherwise, it will answer unicast RS.

    Done.

    I will remove the word suffix, and just say "Interface ID"

    okay, I'll review it again and fix this to the standard way.

    I'm always uncomfortable with expansions in the Abstract, but I'll do that.
