COMMENT:
----------------------------------------------------------------------
I have some non-blocking comments (and nits):
(1) §1: "LISP-GPE MAY also be used to extend the LISP Data-Plane header..." I
think that MAY is out of place because there's nothing normative about the
statement.
ok. I'll fix in -07 with s/MAY/can/.
(2) §3: "If the P-bit is clear (0) the LISP header conforms to the definition
in [I-D.ietf-lisp-rfc6830bis]." I find this statement a little confusing
because even with the bit set, the header still conforms to rfc6830bis, except
for the Nonce/Map-Version field. IOW, it sounds as if the bit makes the header
non-conforming.
ok. I'll fix in -07 with s/conform/is bit-by-bit equivalent/
(3) §3: For clarity, it would be nice to add a figure showing the header with
the P and V bits set.
A similar comment was raised by another reviewer. It was decided that
this document will use the same convention of 6830bis (that doesn't have
a figure with the V bit set).
(4) §3.1: "...the specification of a new encapsulated payload MUST contain an
analysis of how LISP-GPE SHOULD deal with..." s/SHOULD/should In this case
the "SHOULD" is not normative.
ok. will fix in -07
(5) For IP packets, two encapsulation mechanisms exist, the base one defined in
rfc6830bis and the generic one defined in this document. When encapsulating
towards a GPE-capable router, which mechanisms should be used? Should one have
preference over the other? I'm thinking it probably doesn't matter (since the
receiving router can understand both) -- I'm trying to figure out whether there
are operational considerations or guidance that are worth mentioning.
I can't think of a strong reason why one would be better than the other,
and I see no harm in allowing both behaviors. I'd leave the choice to
the implementors.
Thanks,
Fabio
