CURRENT_MEETING_REPORT_



Reported by Sue Hares/Merit and Bill Manning/SESQUINET

Minutes of the OSI IDRP for IP over IP Working Group (IPIDRP)

Agenda


   o Discussion of the Working Group Charter.
   o Review of IDRP for IP Document.
   o ISIS-IDRP Interactions Paper.
   o Next Steps.


Susan Hares (Chair) led the discussions and gave the presentations.

Working Group Charter

A great deal of discussion occurred about the Working Group Charter.
The focus was what documents should be developed.  The documents to be
developed are:


   o IDRP for IP: Merit will implement a version by Nov'92.
   o MIB: Sue will derive from BGPv3.  Not further discussed here.
   o Useage Document.  A great deal of discussion was given to what
     should go in the Usage document.  In the usage document should go:

      -  History of the protocol.
      -  Typical scenarios for Useage IDRP in Internet.
      -  Sample Policy description language.
      -  How IDRP interacts with CIDR and C#.


A great deal of discussion was engaged in about whether interactions to
other protocols belong in a usage document.  It was decided the
interactions should go in separate documents.  Interactions that will
need to be discussed are:  IDRP <-> ISIS, IDRP <->EGP, IDRP <->
BGP2/BGP3/BGP4.

These documents will be new documents added to the Working Group
Charter.  The family tree document will tie these documents together.

Review of IDRP for IP Document

IDRP for IP can not assume correct routing if the addresses used are NOT
globally unique.  Mentioned because some proposal to fix the IP
addressing problems do not guarantee this.  This basic assumption will
be placed in a section in the beginning of the document.

                                   1





A great deal of discussion centered around a QOS flag for RE, and
asynchronous routes.  Many people thought asynchronous routes provide
problems for users, but some people challenged this discussion.

ISIS-IDRP Paper Overview

One goal of the ISIS-IDRP interactions is to allow a BIS to learn things
from the IGP IS-IS. A tutorial was given about this.  The paper can be
obtained from merit.edu in /pub/iso/isisidrp.ps.  This paper was
presented to the SC6 committee during their July meeting which ran the
same time as IETF. BIS can learn network layer reachability information
from IS-IS in three methods:


   o No Summarization:

      -  Skipped over the MIB ways
      -  Mash into the NRLI - use mask

   o Automatic:

      -  Local RDI template

   o Pre-configured


Given some IS-IS changes, BIS can discover each other via IS-IS. IDRP
information can either be tunneled through a domain or injected into the
IGP for transmittal across the domain.  A discussion occurred on how you
choose when to tunnel vs.  inject into the IGP. Tunneling can be based
on overload bit in IS-IS. Dennis Ferguson (CA*NET) suggested we should
ask for this type of feature in IP. We need a general specification on
tunneling, otherwise there will be problems.

Tunneling brings up the issue of encapsulating CLNP in IP or IP in IP.
Vint Cerf suggested that we look at earlier work in multiple
encapsulations.  Vint suggested Paul Tsuchiya's paper on encapsulation
loops.

Action Items


   o Discussion of ASYNC routes on this list.
   o New Charter published by Chair.
   o Document delivered in August.
   o EGP-IDRP interactions document helpers:  Scott Brim, Sue Hares
   o BGP-IDRP interactions document helpers:  Scott Brim, Sue Hares
   o OSPF-IDRP interactions document helpers:  Suggested to catch Kannan
     who wrote BGP-OSPF document.
