CURRENT_MEETING_REPORT_ Reported by George Clapp/Ameritech 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.
