          Acee Lindem: NDMA - wants to start a GIT repository
          Avoid letting Ladha define it to avoid yin to yang conversion
          4) OSPFv3 Extended LSAs Update - 10 Minutes
          - https:
          - Acee Lindem
          See slides
          Acee Lindem: Will open source implement this?
          David Lamparter: No one working on it right now. Looking at SR -
          which may require doing this. But not committed to doing this yet.
          5) OSPF LLS Extensions for Local Interface ID Advertisement - 15 Minutes
          - https:
          - Peter Psenak
          See slides
          Alia Atlas: Not much discussion on the mailing list. If it is stable
          open to early allocation of codepoints but would like to see more
          discussion on the list to reflect that WG thinks this is stable.
          Would like to decide about early allocation of codepoints by IETF100.
          Peter Psenak: There is an existing implementation.
          Alia Atlas: Work based on running code is more mature but it is still a
          pre-standard implementation. Could there be gaps?
          Acee Lindem: Will start discussion to help make a decison about early
          allocation. Less concerned about early allocation requests in OSPF since
          the number of requests are few - unlikely to have collisions.
          (Not like BGP-LS)
          6) OSPF TE Attributes for non-TE Applications Update - 15 Minutes
          - https://datatracker.ietf.org/doc/draft-ppsenak-ospf-te-link-attr-reuse/
          - Peter Psenak
          See slides
          Abhay Roy: Some private comments of support have been received in
          to the public comments of support on the list.
          Alia Atlas: Agree that WG adoption polls have similar results in both
          and IS-IS WGs.
          Les Ginsberg: Consensus on WG adoption exists in both OSPF and IS-IS.
               Question for Alia, can't we follow the consensus?
          Alia Atlas: We don't do voting. We have support from
                multiple affiliations. I have asked Chris Hopps
                for a virtual interim and some more work on use
                cases documents.
          Les Ginsberg: If you look at the history of WGs and drafts, we've
               always adopted drafts with this level of support.
               Why have the WG chairs elected not to adopt the
          Alia Atlas: Look at RFC 7822, are there valid technical
                objections? Case in point, is NVO3 with
                encapsulations. Would like to hear reasons
                for why this is extension is necessary.
          Les Ginsberg: I was in the opposite position for IS-IS Encap
               draft since I didn't think it is necessary.
               WG consensus was to adopt.
          7) OSPF NSSA ECMP to Multiple ASBRs Potential Errata - 10 Minutes
          - https://datatracker.ietf.org/doc/rfc3101/
          - Acee Lindem
          Acee Lindem: Would like to handle this via errata.
          Chris Bowers: Is there no possibility of causing routing loops?
          Is this a  "SHOULD" vs a "MUST"?
          Acee Lindem: Correct
          Other rules insure this cannot happen.
          Chris Bowers: Current implementations - be good to find out what is
          currently deployed.
          Would like to know what existing implementations do.
          Acee Lindem: One known implementation honors it - one doesn't.
          Does open source honor it?
          David Lamparter: We only started doing ECMP in the last year - not sure
          what it does.
          Chris Bowers: Would like more time to look at this.
