(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 complements [RFC8138] and dedicates a flag in the RPL configuration option to indicate whether [RFC8138] compression should be used within the RPL Instance.  The setting of this new flag is   controlled by the Root and propagates as is in the whole network. When the bit is not set, source nodes that support [RFC8138] should refrain from using the compression unless the information is superseded by configuration.

Working Group Summary:

The document was discussed during the IETF 106 and adopted by the WG on Dec 11th 2019. The WG adoption was based on the following:
"-There were positive opinions, including from people who actively contribute to the writing of drafts at ROLL and related WGs, and who contribute to developing or evaluating their implementations.
-There was one opposition, arguing that RFC8138 turn on should be done another way.
-There is no substantiated technical proposal on the table other than draft-thubert-roll-turnon-rfc8138."

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

Not apply.

(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?

(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.

- draft-ietf-roll-useofrplinfo: in last call stage

- draft-ietf-roll-unaware-leaves: : in last call stage


(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.

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 8126).

This specification updates the Registry for the "DODAG Configuration Option Flags" that was created for [RFC6550] -https://www.iana.org/assignments/rpl/rpl.xhtml#dodag-config-option-flags-

(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.

No. This specification updates an existing Registry.

Not apply

(20) If the document contains a YANG module, has the module been checked with any of the recommended validation tools (https://trac.ietf.org/trac/ops/wiki/yang-review-tools) for syntax and formatting validation? If there are any resulting errors or warnings, what is the justification for not fixing them at this time? Does the YANG module comply with the Network Management Datastore Architecture (NMDA) as specified in RFC8342?
