Minutes of the IP over Large Public Data Networks Working Group (IPLPDN)

The IPLPDN Working Group covered the following topics:


   o The IEEE 802.6i draft standard specifying protocol identification
     and encapsulation formats for remote bridging over 60 bit address
     DQDB subnetworks was reviewed and approved.

   o Protocol identification and encapsulation for circuit ISDN (B
     channels) were discussed with members of the PPP group.  The group
     agreed to use the XID procedure to determine the encapsulation
     format.  Andy Malis volunteered to contact Joel Halpern and Lyman
     Chapin to obtain a code point indicating PPP. William Jolitz
     volunteered to write an internet draft on the procedure.

   o An internet draft updating IP over X.25 was reviewed.  Comments
     were received by Andy Malis, who will incorporate the comments in a
     new version of the draft for review at the next IETF meeting.

   o It is anticipated that multiple IP subnetworks will be implemented
     on public data networks such as SMDS, Frame Relay, and X.25.
     Currently, two IP stations on different IP subnetworks implemented
     on the same PDN can only communicate via a router.  The group
     discussed two mechanisms which would allow such stations to
     communicate directly.  These mechanisms would also resolve IP
     addresses to the corresponding PDN addresses (e.g., E.164 and
     X.121).

   o The group agreed to ask the IAB to advance RFC 1209 to the next
     step in the standardization process.  RFC 1209 describes IP over
     SMDS.

   o Parameter negotiation and procedures for automatic configuration
     across Frame Relay permanent virtual circuits were discussed.  The
     group agreed to define a procedure to negotiate data link
     parameters, but thought that work on automatic configuration should
     be done within the network management area.



Issues for the next meeting:


   o Continued work on issues concerning multiple IP subnetworks on the
     same PDN.

   o Specify a mechanism to identify the encapsulate over circuit ISDN

                                   1





     (acquisition of a code point to identify PPP).

   o Review and approval of the draft on IP over X.25.

   o Specify parameter negotiation over FR PVCs.
