Hi, Joe and Ralph,
I am the assigned Gen-ART reviewer for this draft. For background on
Gen-ART, please see the FAQ at
<http://www.alvestrand.no/ietf/gen/art/gen-art-FAQ.html>.
Summary - this draft is almost ready for publication as a Proposed Standard.
It is short, and clearly written.
I have four observations - there may be DHCP conventions I don't know about,
but this is how things look to me.
- The relationship between "Length" and "Prefix-Length" seems
underspecified. If what you are saying is
Length - the length of the entire attribute, in bytes. At least 4 (to
hold Type/Length/Reserved/Prefix-Length for a 0-bit prefix), and no larger
than 20 (to hold Type/Length/Reserved/Prefix-Length for a 128-bit prefix)
Prefix-Length - the length of the prefix being delegated, in bits. At
least 0 and no larger than 128 bits (identifying a single IPv6 address).
I'm guessing, and if you are actually saying something else, I don't know
what it could be :-)
- Does "Reserved - Always set to zero" ever get validated as zero by a
receiver?
- I completely missed the three-line, two-row "table" at the end of Section
3. If you could at least indent it, and maybe even draw ASCII boxes around
it, the specification would be much easier to grok.
- It would also be nice to have a pointer to a reference for the definition
of "Framed-IPv6-Prefix" in Section 3, but that's extremely minor.
Please look at these comments along with any other Last Call comments you
may receive.
Thanks,
Spencer Dawkins
