Re: [Gen-art] Gen-art last call review of draft-ietf-idr-as-private-reservation-03

["Susan Hares" <[e-mail]>]

Jon and Elwyn:

These drafts are working toward a larger goal - the eventual update of the
RFC 4271 with current practices.   Getting consensus on these items except
in very small pieces have been extremely difficult. 

Eventually, these will be all rolled up into larger documents that refer to
these smaller documents. 

The reason behind this is tactical. The smaller drafts allow people to stop
doing bad things to BGP immediately.  We have new implementation coming due
to the explosion in the Data center market.  Therefore, vague pieces in
RFC4271 must be plugged now. 

It seems that I really should get around to writing up the process on the
IDR web page and an internet draft. 

Thanks for your hard work, 

Sue

Elwyn -

Yes, I agree this is a reasonable change to remove all of the "suggestion"
text in the IANA considerations area and will make sure it is in the next
draft if one is required, either way all of that text will be removed by
IANA, who has also just sent back their review of the actions required.

On your second comment, currently being published as an RFC is a draft
reserving as0 in a similar fashion, so I do think it's most appropriate as a
second doc.. and I really have trouble tying these reservations to a RFC
about Private ASN's.   If no doc is published, the good news is that IANA
has already reserved the last number (with no justification).  Again, if
IESG or others feel strongly it should be in this draft, I will try to work
out some text to justify their reservations...

Thanks!

Jon

As specified in the registry, allocations in this registry are either by
IETF Concensus (i.e. a suitable RFC such as this draft is intended to
be) or request from a RIR. Thus it isn't a matter of suggesting to IANA but
telling them what the IETF want done - so this draft should be definitive -
and what you said about WG concensus constitutes the values to be used
unless somebody else in the IETF manages to alter the concensus which seems
unlikely.

Yes, that's fine and as expected.

Publishing a separate draft seems a bit overkill but clearly that's not my
decision. ;-)
