COMMENT:
----------------------------------------------------------------------

Thank you for the work put into this document. It is really easy to read with
very nice ASCII art figures.

Nevertheless, please find below some non-blocking COMMENTs (and I would
appreciate a response from the authors) and NITS.

I hope that this helps to improve the document,

Regards,

== COMMENTS ==

-- Section 1 --
As my esteemed colleague from East US Coast, I liked the introduction but I
would prefer to have the EARO acronym expanded.

-- Section 2.3 --
I wonder whether using "6LBBR" would be more readable and consistent (with
"6LN" and "6LBR") than using "6BBR"

-- Section 3 --
Should the method to achieve "ensure that the Address is not duplicated over
the Backbone" be specified? E.g., DAD ?

-- Section 3.2 --
"The RS sent initially by the 6LN(STA) is transmitted as a multicast
   but since it is intercepted by the 6BBR, it is never effectively
   broadcast."
Perhaps worth mentioning "layer-3 multicast" hence "layer-2 broadcast"... And
"never... broadcast" it would important to mention the scope of the broadcast.
This ambiguity about layer & scope happens quite often in the document.
Knowledgeable readers will understand of course but what about less
knowledgeable ones?

== NITS ==

I found the use of acronyms a little too heavy, complicating the reading for
little benefits: e.g., ODAD = Optimistic DAD, SLLAO = Source LLA Option. On the
contrary, well-known acronyms are not used :-) E.g., multiple instance of "Link
Local addresses" rather than the well-known "LLA".

In the same vein, it is sometimes "Layer 2 Address" and other times "MAC
address"
