\[6:30\] Intro (chairs)

*   Note Well, thanks to Alvaro (outgoing responsible AD), welcome John

*   Agenda bashing
*   Draft status

\[6:39\] draft-ietf-roll-aodv-rpl (Ines + Charles Perkins)

*   Ines provides background to the technology
    *   reactive routing, P2discovery by originNode, akin to AODV.

*   Charles: Pascal had comments on when to prefer AODV-RPL compared to
    legacy RPL. Added text in -16 to address this point.
    *   Shorter routes than going through root, less congestion around
        root.

*   last WGLC did not return comments.
*   routing dir review (Tony), next draft version (-17) in the next few
    days
*   improved language for describing instance matching between RREQ and
    RREP
*   no questions/comments for Charlie at this time

\[6:51\] draft-ietf-roll-dao-projection (Ines)

*   Ines provides goal & background to the technology
    *   presents additions/extensions to RFCs 6550, x ,8138

*   Status
    *   review from routing directorate delayed

\[6:58\] draft-ietf-roll-nsa-extension (Dominique)

*   Dominique provides the status and history of the draft
    *   draft expired, reached to the Authors, Aris is working on the
        draft

*   Dominique provides an overview of the technology
    *   improves path diversity by selecting parents based on their
        "ancestors"

*   AD review discussed & next steps presented
*   Pascal provides additionnal explanation
*   No questions/comments for Dominique at this time

\[7:09\] draft-ietf-roll-rnfd (Dominique)

*   Dominique provides the status and history of the draft
    *   algorithm and protocol is defined, WG agrees on the problem, to
        decide on adopting proposed solution

*   Dominique provides an overview of the technology, specs
*   Dominique reviews questions/comments on the draft (raised at the
    June 2022 interim meeting) and Konrad's answers on the ML
*   Dominique asks Pascal if the current solution is adequate
    *   Pascal says we could go to WGLC with this document, good for
        DODAG reliability, which is needed.
    *   Pascal: but there are other solutions for reliability, e.g.:
        double the Roots and toggle between them (hot standby).
    *   Pascal: can RNFD help in the hot standby situation, to speed up
        the toggling? Would make the draft useful in a wider range of
        use cases.

*   Dominique: we'll examine this in the next interim. Pascal, willing
    to contribute to the discussion?
    *   Pascal willing to help with comments

\[7:26\] draft-ietf-roll-mopex (Ines)
