          LSVR WG Status:
          ---------------
          * YANG is MIA
          * Next steps = LSVR Re-charter for IETF109
          
          Keyur gives update that LSVR Yang model is being worked. First version
          should be up and running and submitted to IETF soon.
          
          Presentations:
          --------------
          
          * Keyur Applicability Doc Update
           o Version 5 was submitted in March
           o Comments from Boris were incorporated into version 6 (examples and
           text updates).
           o Version 6 was submitted by Acee
          
          * Keyur BGP SPF Doc Update by Keyur
           o Version 9 was submitted in May
           o Mulitiple implementations since IETF 107
           o Comments have been addressed from routing directorate
           o New contributor
           o Yang model in progress
          
          * Keyur Implementation Draft for BGP-SPF by Keyur
           o Two implemtnations now
             1. ArcOS
             2. FRR Routing Stack
           o Review implementation report (see slides for chart)
           o Alvaro Question: - request to add implementation to draft.
               Response: there’s a separate implementation draft. Add a new
               section?
               AR: link or pointer would work
               Gunter: added to shepard draft and wiki suggestion
               AR: need as much visibility as possible
               Jacob: reachout out for testing out implementation
               Acee: as far as implementation drafts go, he has some
               suggestions. would also like to review the results
               Anurag: mentions in the draft about dampining SPF calculations. is
               that to allow for better scalability?
               Answer (keyur): from an implentation standpoint, wanted to pace it
               incase there’s a lot of updates.
               Anurag: is it stateful?
               Keyur: Stateful behavior have 3 phases. Different implemtnations
               can do it different. the 3 default phases in BGP were replaced with
               SPF comuptation to install router the RIB
               Anurag: is this a local rib or adj out?
               Keyur: this is an implementation specific detail. the draft allows
               flexibility
               Anurag: is there a recommendation in the draft?
               Keyur: no recommendation in the draft.
               Acee: comment on the backoff. all IGPs have some kind of backoff. in
               the draft there’s a recommendation.
          
          * Randy Presentation for L3DL:
           o Primary Goal: Discovery of L3 topology and liveness. Not a routing
           protocol.
             * Jorg Ott did an early review of the draft
             * -06 was reviewed
           o 2 python implementations
             1 is opensource (LSoE)
             1 is in ArcOS (not open source) in GoLang
          
          * Randy Presentation on L3DL Signing
            o Some simple security additions
            o Open PDU has Auth Type and Length with Signature info
            o Key in open PDU is public key
              * 2 General verifications:
                1. TOFU. Trust on the first use (open) and subsequent PDUs use that
                2. PKI Based. Adds a trust anchor. This is not x509
            o question from John Scudder: one thing that he runs into. what’s your
            manadory to implement algorithm.
            o Randy: currently not one.
            o This draft describes the L3LC ULPC PDU which describes what the
            upper layer protocol.
            o Descriptions of UPLC information for BGP
