This I-D has some of the usual things wrong with it that need fixing at
some state and, as ever, I like to see the editors fix at least some of
them before adoption rather than leaving them until later, since they
then seem to linger, perhaps until WG Last Call or IETF Last Call (yes,
I am thinking of WG such as MPLS:-)

There is a fundamental (to me) principle in engineering of get it right
first time, or at least as early as possible; later means more
expensive, more time consuming for everyone involved.  I link this to
the discussion on the main IETF list of the difficulty of finding ADs
because so much time is involved in being an AD; yes, and part of that
is us giving them poor quality documents with defects that could have
been fixed even before adoption..

This I-D

- fails to mention whether or not it is NMDA compliant in the Abstract
and Introduction

- fails to use the current definitions of terminology from RFC8342

- references the old version of RFC2119 key words

- has no Note to the RFC Editor asking them to replace the YANG module
dates with date of publication.  I suggest a Note asking them to replace
XXXX with the number assigned to this I-D at the start of the I-D rather
than asking them to replace 'draft-ding-rtgwg-arp-yang-model-02 ' which,
should this I-D be adopted, will be wrong

- has no Copyright statement in the YANG module

- lacks references for several imported modules.

- starts Section 4 well with a good sentence but fails to mention most

- has serious formatting problems with the text in the YANG module with
lines being way too long for an RFC (it is probably not a coincidence
that other I-Ds have had the same problem -  the right options in pyang
fix this AFAIK)

- has no IANA Considerations; no IANA Considerations means that you are
not producing a YANG module no matter what it looks like.

- Security Considerations are much better than usual but lack detail of
sensitive nodes

- Tree diagrams has the right reference but then spoils it by including
text about the symbols

- has out of date references
which belie the claimed date of  June 28, 2018 for this I-D; 2018-01-27
looks more like it:-)

- has arp as a Informative Reference - Normative I think.

I note that there is  no IPV6 in the examples but that seems right since
ARP is IPv4.

The English is flaky in places but I am fine with that; that can be
fixed once the text has been discussed and agreed - in fact there is no
point in producing perfect English if we are then going to discuss and
change it - whereas the points above can mostly be fixed before now.
