Review of draft-ietf-roll-aodv-rpl-10
Peter van der stok, 15 April 2021
In general, the document is well written. By looking regularly into RFC 6550, I
am rather sure that I could implement the protocol. The question remains how
this draft relates to RFC 6997. When the WG decides that this draft replaces
RFC 6997, then it would be good to copy some text from 6997 to this draft,
because RFC 6997 is more explicit about the use of RPL parameters as specified
in RFC 6550 and presents more explicit motivation.
Many thanks for this document
peter

Some suggestions for the text follow here:
Page 14, lines 3 and 4;
OLD: ART Options and within
New: ART Options. Within
Page 14, line 9
distinguished -> generated
page 14 section 6.2.1
OLD: does not belong to the RREQ-Instance
NEW: has not joint the RREQ-Instance
Joining is used in Step 1, 2nd paragraph.
Question: what is the "best previous RREQ"?
Page 14, Step 1, 2nd paragraph
OLD: router's Rank would not exceed
NEW: router's Rank does not exceed
Page 15 end of Step 3;
Question: What is a "stale sequence number"?
Page 15, section 6.2.2
OLD:
If the OrigNode tries to reach multiple TargNodes in a single RREQ-Instance,
one of the TargNodes can be an intermediate router to the others, therefore it
MUST continue sending RREQ-DIO to reach other targets.
NEW:
If the OrigNode tries to reach multiple TargNodes in a single RREQ-Instance, it
MUST continue sending RREQ-DIO to reach other Targets because one of the
TargNodes can be an intermediate router to the others.

NEW for a given
Page 17: the terms occupied RPLInstanceID, and second RPLInstancID are
difficult to parse. Maye be use received RPLInstanceID and shifted
RPLInstanceID? Further on you use original RPLInstanceID, is that a third one?
Question: what does "shifted into another integer" mean?
Question: who or what chooses the shift value, when is it set and into which
RREP-DIO field is the shifted value set?
Page 18 Step 2; Are multiple addresses possible in the ART option. I just
understood there is only one per RPLInstanceID (shifted or not).
Page 18 Step 3, As above
Stale sequence number?
