I have been selected as the General Area Review Team (Gen-ART)
reviewer for this draft (for background on Gen-ART, please see
<http://www.alvestrand.no/ietf/gen/art/gen-art-FAQ.html>http://www.alvestrand.no/ietf/gen/art/gen-art-FAQ.html).
Please wait for direction from your document shepherd
or AD before posting a new version of the draft.
This document is almost ready for publication as an Informational
RFC. There is one item that should be fixed before publications, and
several items that should be changed given that a respin is needed anyway.
Yours,
Joel M. Halpern
Moderate:
1) In the MPLS recommendation, it is recommended that labels be
uniformly distributed between 0 and 2^20. Given that the labels
0-15 are reserved for special function, and often have special
processing or discarding, it strikes me that test equipment may well
get unexpected results if it randomly attempts to use those for
normal operations. I would recommend checking the the MPLS standards
as to the current reserved range, and making sure the random
assignment stays out of that.
Minor:
IDNits alerted the fact that the IPv4 address used as
samples in Appendix C are not RFC 3330 documentation values
(192.0.2.0/24). Similarly, the IPv6 example does not use the IPv6
documentation block assigned by RFC 3849 (2001:DB8::/32)
In section 4.2, in describing how to create the MAC address,
the upper byte is anded with 0xFC to clear the global/local and
unicast/multicast bit so that the address will be a global
multicast. there are two minor issues here:
Using a global MAC address construct from a random number and a
port number is probably appropriate, but violates the standard. It
would probably be a good idea to acknowledge this fact, and explain
why global (rather than local) addresses need to be used.
The text refers to the two bits that are being controlled as the
"high order two bits of taht byte." While those are the first two
bits that will be clocked out over the ethernet, they are not the
"high order" bits in most peoples understanding of the term.
