Hi Peter,
since we cleared the minor issues we can move to the major issues.
The IANA Consideration section was not exactly an example of clarity.
So better to rewrite it….
Hereafter you can find my replies to your comments and at the end you’ll find
the proposed text for the new IANA Consideration Section.
Let me know if it works for you.
ciao

Major issues:
This draft does not give much management perspective nor many procedures,
perhaps because it calls itself a framework for management.
Indeed, it is a guideline document.
Having said that, RIPE had no difficulties in implementing the registration
service.
It mostly lists
data to be captured and discusses renewals periods. It does not discuss how
requests are vetted or what would cause one to be disapproved, if that's
even a possibility.
In Section 5, last bullet, and point 4 of section 6 there is information on
what should be provided in order to have a soul registration request.
It does not give any recourse for disapproved requests.
It does not specify how a request (whether pending or approved) is abandoned
or surrendered. Consider section 3 of RFC 5226 as possibly being useful,
for example.
In the new IANA Considerations section FCFS policy is now spelled out.
Given the details that the draft does discuss, it really needs
to have an actual discussion of management procedures
Can you be more specific on whether something else is missing?
or give a pointer as
to where these are discussed or how they are to be executed in concert with
the framework.
Section 10 (IANA Considerations): This section seems inadequate from an RFC
5226 perspective as well as simply throwing a lot on IANA to provide the
lookup mechanism without giving any further guidance than a bunch of
protocols (RDAP, WHOIS, HTTP, etc.) Also see RFC 5226, Section 4.2.
Specific requirements for IANA need to be clearly spelled out in this
section, especially as there are potentially multiple registry operators
that are somehow involved in prefix allocation requests.
As for the latest agreement with RIPE, actually IANA does not need to do
anything.
This is now speed out in the new reviewed section.
This is not at all
made clear in the document how coordination between registry operators and
IANA is to be carried out.
Since RIPE takes over all of the service, and will be the only one,
there is no specific coordination to be performed.
It's not even clear whether users are supposed
to be directly requesting prefixes from IANA or whether IANA should reject
such requests.
In the latest version is spelled out that requests have to go to RIPE.
There's no guidance on how IANA recognizes valid requests.
Valid request are the ones respecting the content of this document.
This is now spelled out in the new text.
There's no guidance on whether there is a limit to the number of requests
that may be made by an organization or individual.
There is no limit. This is now spelled out in the new text.
The document notes a
hierarchical distribution of the address space but gives no further guidance
to IANA on how this hierarchy is to be organized and how registration
requests impact the hierarchy.
The second bullet of section 5 has been deleted (as you also suggested
elsewhere).
Due to the limited duration of the experiment one single registration operator
(RIPE) is sufficient.
In short, a whole lot more needs to appear
in this section and in the text leading up to it.
Hopefully the proposed text fills the holes….
Then again, I'm no LISP expert, so I could be completely off-base here. :-)
At this point actually more than you think ;-)
%%%%%% NEW IANA SECTION PROPOSED TEXT %%%%%
IANA Considerations
IANA allocated the following IPv6 address block for experimental use
as LISP EID prefix [I-D.ietf-lisp-eid-block]:
o Address Block: 2001:5::/32
o Name: EID Space for LISP
o RFC: [I-D.ietf-lisp-eid-block]
o Further Details at: http://www.iana.org/assignments/
iana-ipv6-special-registry/iana-ipv6-special-registry.xhtml
In order to grant requesting organisations and individuals exclusive
use of EID prefixes out of such reserved block (limited to the
duration of the LISP experiment as outlined in Section 7) there is an
operational requirement for an EID registration service.
Provided that the policies and requirements outlined in Section 4,
Section 5, and Section 6 are respected, EID prefix registration is
accorded based on a "First Come First Served" basis.
There is no hard limit in the number of registrations an organization
or individual can submit as long as information described in
Section 6 is provided, in particular point 4: "Experiment
Description".
IANA and RIPE NCC agreed for the latter to run such service on behalf
of the former, for the duration of the experiment and following the
procedures outlined in Section 10. Therefore, this document has no
IANA actions.

No problem, Luigi. I'll just be happy if my feedback proves helpful.
It actually is and I realise that we did a pretty poor job in handling your
review. Sorry for that.
In order to progress, let me propose a incremental approach:
Hereafter I put and comment everything that is minor issues.
Let me know if you are OK.
Once we clear them we will go to the beefy stuff (aka major issues).

Minor issues:
Page 1, Abstract, 2nd sentence, "sub-prefixes": This term is not
defined and suffers from the same problem as ietf-lisp-eid-block in
that is also used once in that document but not further described.
There appears to be some confusion between the use of prefix and sub-prefix
that should be rectified.
Prefix in this document appears to generally mean sub-prefix with
regards to the experimental block, but this is not made clear.
What about the following text:
This document proposes a framework for the management of the
LISP EID Address Block. The framework described relies on hierarchical
distribution of the address space, granting temporary usage of prefixes
of
such space to requesting organizations.
PEY> I think that will finesse the prefix/sub-prefix issue.
Page 4, Section 5, items 1 and 2: considering that multiple
registries may be assigning these (sub-)prefixes and that they must
be globally unique, is there a mechanism to ensure this other than
waiting for the inevitable IANA clash between simultaneous registrations?
Fair enough. This was a degree of freedom we left to IANA. The requirement is
globally uniqueness, how IANA, registries, or anybody else running the
“Registry" want to sync to respect the requirement is something left as
“implementation specific”.
My personal take on this point is that since the experiment has a limited
duration and because it is very likely that the only registry running the
service will be RIPE NCC, there is no need to over-engineer this point.
PEY> Somewhat agreed in that the actual usage should not cause any conflicts.
Note that S5 item 2 raises the concept of additional registries, and hence
my concerns. However, do note that Jari Arkko has raised concerns with the
registry as well, so you may want to add language (and even consider removing
S5 item 2) in order to reduce the confusion.
Nits:
Page 3, Section 2, 1st paragraph, 1st sentence: change "separates" to
"separate”.
Thanks, will be fixed in -07.
Page 3, Section 2, 3rd paragraph: change "organisation" to "organization".
All other uses of the word in the document have been spelled
"organization", so make this usage consistent with the others. Or
change them all to "organisation" if that's preferred. Pick one.
Thanks, will be fixed in -07.
Page 3, Section 3, 1st sentence: delete an extraneous space after the
open parenthesis.
Thanks, will be fixed in -07.
Page 3, Section 4, 1st sentence: insert "for" between "request" and
"registration".
Thanks, will be fixed in -07.
Page 4, 1st full paragraph, 4th sentence: insert "be" between
"should" and "no”.
Does not apply anymore.
Page 4, Section 5, item 3: insert a comma after "information".
Change "though" to "through”.
Thanks, will be fixed in -07.
Change "I-D.ietf-weirds-rdap-sec" to RFC 7481.
This is already fixed in -06.
Change "whois" to "WHOIS". Change "http" to "HTTP”.
Thanks, will be fixed in -07.
Page 5, Section 6, 2nd paragraph: delete the comma after "registry".
Page 5, Section 6, item 1: insert "the" between "In" and "case".
Append a comma after "prefix”.
Thanks, will be fixed in -07.
Page 5, Section 6, item 1: despite being based on the IANA PEN form,
how about adding a sub-item (d) for the organization's website? This
might allow for user disambiguation of registrants with similar names.
It does not harm actually. Will be added in -07.
Page 7, 1st partial paragraph, 1st partial sentence: insert "as"
between "so" and "to”.
Thanks, will be fixed in -07.
Page 7, 1st full paragraph: delete the comma after "allocation”.
Thanks, will be fixed in -07.
Page 7, Section 8, 2nd paragraph: delete the comma after "reasons”.
Thanks, will be fixed in -07.
Page 7, Section 10, 2nd paragraph, 2nd sentence: insert "an" between "for"
and "EID”.
This is already fixed in -06.
Page 8, Section 11.1, [I-D.ietf-lisp-eid-block]: change the "-09" to "-11”.
We are now at -12 and will keep the reference updated.
Page 9, Appendix A: This appendix is almost wholly superfluous and
unnecessary to understanding the core of the document. Most terms
that appear in the appendix make no other appearance in the body of
the document and the definition of these terms does not inform a
reading of the body of the document. I'd recommend dropping the
appendix and elsewhere in the document throwing in a pointer to RFC 6830.
This is a fair point and it has been raised also by other.
Let me answer in the same way: What is the aim in having such appendix?
- It is an appendix so its content is clearly optional.
- It clearly spells out that is not normative content but only to avoid the
reader digging around to find the definitions.
- Some readers that do not know LISP might find it handy to have it around.
PEY>I might suggest a separate Informational RFC that provides the
information contained in the appendix for reference when using all of the
LISP documents rather than burying it in a management framework. But I also
recognize that this may not be an expeditious way to progress things, so do
no more than take my thoughts under advisement.
ciao
Luigi

Hi Peter,
Back in April we indeed did not sent you a specific feedback.
Reason is that we received several comments/reviews and batched everything
in a new I-D, with sending specific feedback to all.
The correct sentence is: “without sending specific feedback to all”
I should really start to proofread my mails before hitting the send
button ;-)
ciao
L.
Yet, if you are unsatisfied on how we addressed the issues we certainly
need to do more work.
Give me some time to go again thoroughly through your first review and I’ll
get back to you with a specific feedback.
Thanks for your time spent on this document.

Summary: This draft has serious issues, described in the review, and
needs to be rethought. [Not ready]
The draft attempts to specify the framework for the management of
experimental LISP EID sub-prefixes, but really could use some
additional work to flesh out the management aspects that are left unsaid.
This draft fixes only two minor nits I raised in my review of the
-04 version. Nothing else has been addressed, nor have I received
any feedback on that review. In light of this, I have little new to add.
It is possible that the agreement between the IANA and the RIPE NCC
will alleviate the major concern I had with the draft, but not being
privy to that agreement, I can't make that determination.
