IS-IS WG Meeting Minutes
   Scribe: Acee Lindem (acee@cisco.com)
   
- Intro, Adminastriva, Document Status - (Christian Hopps, Hannes Gredler)

- IS-IS Auto-Configuration - Les Ginsberg (See slides)
  https://datatracker.ietf.org/doc/draft-ietf-isis-auto-conf
   Les: Feels next revision is ready for last call.
   Hannes: Implementations?
   Les: Not that I know of.
   Bing Liu: Believes there is an implementation in progress but it
             doesn't reflect the latest version.

- Advertising TE protocols in IS-IS - Chris Bowers (See slides)
  https://datatracker.ietf.org/doc/draft-hegde-isis-advertising-te-protocols
  Les: Propose that the problem is the same in both IGPs and use
       cases are the same.
  Chris Bowers: I agree. There are cases where attributes will clearly 
                be the same for all application (e.g., SRLG).
  Acee: Disagrees that there are not use cases for different SRLGs per
        application.
  Adrian Farrel: Please comment on a solution with separate instances of 
                 the IGP for separate applications.
  Stephane Litkowski: Could use multiple topologies.
  Chris Bowers: Multiple instance brings more complexity.
  Shraddha: Doesn't like multi-instance in this case. 
  Les: Duplication of topologies for attribute advertisement also 
       introduces complexity

- NVO Control Plane Protocol Using IS-IS - Xiaohu Xu (See slides)
  https://datatracker.ietf.org/doc/draft-xu-isis-nvo-cp
  Paul Unbehagen:IEEE experience with IS-IS was seamless. Where is this implemented?
  Xiaohu: Can be implemented on virtual or real switches 
  Paul: Trying to make this work on virtual switch was difficult. Implemented
        IS-IS on leaf node. May want to look at what we did.     
  

- IS-IS Routing with Reverse Metric - Naiming Shen (See slides)
  https://datatracker.ietf.org/doc/draft-ietf-isis-reverse-metric
  Naiming: WG document for quite awhile. 
  Hannes: Implementations?
  Naiming: Not that I know of.
  Uma Chunduri: Feels this draft is very useful.  

- IS-IS Routing for Spine-Leaf Topology - Naiming Shen (See slides)
  https://datatracker.ietf.org/doc/draft-shen-isis-spine-leaf-ext
  Naiming: Requests WG adoptions
  Chris Hopps: Did extensive review and comments will be posted to
               the IS-IS list.
  David Lamparter: Similar to HOMENET approach with just OL bit.
                   Believes it is a sound approach.
  Hannes: Could use mesh groups as well.
  Naiming: Yes - but mesh groups only solves problem of flooding reduction. 
           This proposal reduces requirements on leaf node implementations.

- Carrying Geo Coordinates Information In IS-IS - Naiming Shen (See slides)
  https://datatracker.ietf.org/doc/draft-shen-isis-geo-coordinates
  Naiming: Request WG adoption
  Acee: Only different for OSPF is that a link-scoped RI LSA is used for 
        signaling on a link as opposed to IS-IS using IS-IS IIH.  

- IS-IS Extensions for Segment Routing - Stefano Previdi (See slides)
  https://datatracker.ietf.org/doc/draft-ietf-isis-segment-routing-extensions/
