IETF OSPF WG Minutes 
  Chairs: Acee Lindem and Abhay Roy 
  Scribe: Yi Yang (yiya@cisco.com)

   * OSPF WG Document Status (Acee Lindem) - See slides 
     - OSPF TE Metric Extensions 
       Alia Atlas: Document has been udpated and she believes all comments
                   resolved. 
     - OSPF Transport Instance:
         Igor Bryskin: What is the advantage of transpor instance when 
                       you have multiple instance support in OSPF. 
       Acee:
          1. Only need to flood required information - no topology or
             prefixes. 
          2. Support of remote neighbors. 
      Alvaro Retana: Do you want doc for use cases?
      Acee Lindem: I'd rather have implementation, but a use case document
                   would also probably be helpful. 

   * OSPFv3 Authentication Trailer (aka, RFC 6506Bis) - See slides. 
        Acee Lindem: Going to confirm on list that this is WG document. AD
                     sponsored work. 

   * OSPFv3 Auto-config (Acee Lindem) - See slides. 
      Fred Baker: Could set the default per interface type. 
      Acee: I could -- but then there is default cost issue on wireless
            interface.
      Alvaro Retana: Clarify the use case on hello timer, is this for system
                     wide bootsup, or for off and on case?
      Acee Lindem: Yes.
      David Lamparter: should differentiate b/w MANET and HOMENET use cases. 
      Acee: I agree. I don't feel homenet implies MANET> 

    * OSPF Extensions for Maxmumilly Redundant Trees (MRT) Fast Reroute (FRR) 
        (Alia Atlas) - See slides. 
       Acee: Whats advantage over remote LFA?
       Alia: Remote LFA requires more computation.
       Igor Bryskin: What mechanism to use to detect local link failure.
       Alia: Same as LFA.
       Igor: You have 2 disjoint trees?
       Alia: Only one will be used for a specific destination. But
             different destination can use different tree. 
       Igor: Does it work in Multi area topo?
       Alia: Yes. independent from Area to area.
       David Lamparter: OSPFv3 Multi-Topology (MT) for MRT?
       Alia Atlas: Not there yet until OSPFv3 MT is ready.
       Michael Barnes: Mutli-Topology (MT) is pretty much dead for OSPF, not 
                       worth it.
       Huaimo Chen: Multi-Topology document is there.
       Acee Lindem: Michael means in practice it's dead.
       Huaimo Chen: Use option bit in router information TLV instead of Router-LSA
                    bits. 

    * OSPFv3 LSA Extendability (Acee Lindem) - See slides. 
       Peter Psenak: It will be useful to originate 2 sets of LSAs in old formats
                     and/or new format.
       Acee Lindem: Will work with Peter.
       David Lamparter: Why not convert between old and new LSAs at interface?
       Acee Lindem: Origination uses existing code better, at the cost of
                    database size.
       Peter Psenak: Inital use this for new LSAs for new info other than SPF.
       David Lamparter: For Segment Routing and Homenet, will new LSAs be used? 
       Acee Lindem: Yes, you will have to use them. 
       Acee Lindem: Will update with comments so far after IETF and request
                    WG adoption. One of the highest priority draft due to other
                    drafts being dependent.
