Hi!

This e-mail is to request the publication of draft-ietf-rtgwg-ordered-fib-07 
(Loop-free convergence using oFIB) as an Informational RFC.  The corresponding 
Document Writeup is included below.

Thanks!

Alvaro.


(1) What type of RFC is being requested (BCP, Proposed Standard, Internet 
Standard, Informational, Experimental, or Historic)? Why is this the proper 
type of RFC? Is this type of RFC indicated in the title page header?

Informational; it documents a valuable mechanism developed by the WG to prevent 
transient loops.

Yes, the title page indicates the correct type.

(2) The IESG approval announcement includes a Document Announcement Write-Up. 
Please provide such a Document Announcement Write-Up. Recent examples can be 
found in the "Action" announcements for approved documents. The approval 
announcement contains the following sections:

Technical Summary:

This document describes a mechanism for use in conjunction with link state 
routing protocols which prevents the transient loops which would otherwise 
occur during topology changes. It does this by correctly sequencing the FIB 
updates on the routers.

Working Group Summary:

No issues.  There is consensus in the WG to proceed with publication.

Document Quality:

This document presents the general mechanism and operation of oFIB, it doesn't 
define routing protocol-specific extensions — which means that there are no 
implementations possible, but also no further work is planned at this time.  
The document has no substantive issues.

Personnel:

Alvaro Retana is the Document Shepherd.

Adrian Farrel is the Responsible Area Director.  [Stewart Bryant is the AD 
assigned to the WG, but he is an author.]

(3) Briefly describe the review of this document that was performed by the 
Document Shepherd. If this version of the document is not ready for 
publication, please explain why the document is being forwarded to the IESG.

The document (currently in it's 7th iteration) has been thoroughly reviewed.  
Comments have been made by the Document Shepherd related to clarity, form and 
content.  All comments have been addressed.  The document is ready for 
publication.

(4) Does the document Shepherd have any concerns about the depth or breadth of 
the reviews that have been performed?

No concerns.

(5) Do portions of the document need review from a particular or from broader 
perspective, e.g., security, operational complexity, AAA, DNS, DHCP, XML, or 
internationalization? If so, describe the review that took place.

N/A

(6) Describe any specific concerns or issues that the Document Shepherd has 
with this document that the Responsible Area Director and/or the IESG should be 
aware of? For example, perhaps he or she is uncomfortable with certain parts of 
the document, or has concerns whether there really is a need for it. In any 
event, if the WG has discussed those issues and has indicated that it still 
wishes to advance the document, detail those concerns here.

N/A

(7) Has each author confirmed that any and all appropriate IPR disclosures 
required for full conformance with the provisions of BCP 78 and BCP 79 have 
already been filed. If not, explain why?

Yes.  The question has been raised throughout the process.

(8) Has an IPR disclosure been filed that references this document? If so, 
summarize any WG discussion and conclusion regarding the IPR disclosures.

Yes, document has an IPR disclosure attached from the authors.  No concerns 
have been raised in the WG.

(9) How solid is the WG consensus behind this document? Does it represent the 
strong concurrence of a few individuals, with others being silent, or does the 
WG as a whole understand and agree with it?

This document has been a WG item for about 6 years.  During this time the 
mechanism (application and potential implementations) have been discussed in 
depth.  There is strong consensus to publish this document as an Informational 
RFC.

(10) Has anyone threatened an appeal or otherwise indicated extreme discontent? 
If so, please summarise the areas of conflict in separate email messages to the 
Responsible Area Director. (It should be in a separate email because this 
questionnaire is publicly available.)

No.

(11) Identify any ID nits the Document Shepherd has found in this document. 
(See http://www.ietf.org/tools/idnits/ and the Internet-Drafts Checklist). 
Boilerplate checks are not enough; this check needs to be thorough.

Only nit to point out is that 6 authors are listed.  The authors have been made 
aware and are prepared to request an exception before publication.

(12) Describe how the document meets any required formal review criteria, such 
as the MIB Doctor, media type, and URI type reviews.

N/A

(13) Have all references within this document been identified as either 
normative or informative?

Yes.

(14) Are there normative references to documents that are not ready for 
advancement or are otherwise in an unclear state? If such normative references 
exist, what is the plan for their completion?

None exist.

(15) Are there downward normative references references (see RFC 3967)? If so, 
list these downward references to support the Area Director in the Last Call 
procedure.

No.

(16) Will publication of this document change the status of any existing RFCs? 
Are those RFCs listed on the title page header, listed in the abstract, and 
discussed in the introduction? If the RFCs are not listed in the Abstract and 
Introduction, explain why, and point to the part of the document where the 
relationship of this document to the other RFCs is discussed. If this 
information is not in the document, explain why the WG considers it unnecessary.

No.

(17) Describe the Document Shepherd's review of the IANA considerations 
section, especially with regard to its consistency with the body of the 
document. Confirm that all protocol extensions that the document makes are 
associated with the appropriate reservations in IANA registries. Confirm that 
any referenced IANA registries have been clearly identified. Confirm that newly 
created IANA registries include a detailed specification of the initial 
contents for the registry, that allocations procedures for future registrations 
are defined, and a reasonable name for the new registry has been suggested (see 
RFC 5226).

There are no IANA considerations which arise from this document.

(18) List any new IANA registries that require Expert Review for future 
allocations. Provide any public guidance that the IESG would find useful in 
selecting the IANA Experts for these new registries.

N/A

(19) Describe reviews and automated checks performed by the Document Shepherd 
to validate sections of the document written in a formal language, such as XML 
code, BNF rules, MIB definitions, etc.
