- Area Summary reported by Bob Hinden/Sun
-
- Border Gateway Protocol Working Group (BGP)
-
- The BGP-4 Internet Draft was discussed. The Group received numerous
- comments which resulted in many changes to the document but did not
- change the resulting protocol. The editors will proceed to incorporate
- these changes and then post the result to the Working Group mailing
- list. If there are no further changes, the Working Group will present
- this to the IESG for Proposed Standard.
-
- The BGP Communities' attributes was presented and discussed. This is an
- optional attribute which is useful for configuring BGP to help enforce
- Acceptable use Policies (AUP). A revised specification will be posted to
- the mailing list and then subsequently submitted to the IESG.
-
- The BGP4/OSPF interaction document was discussed. A revised
- specification will be posted to the mailing list and the submitted to
- the IESG.
-
- The BGP-4 usage document was discussed but closure was not reached. It
- is still unclear as to how much aggregation should happen by default
- with BGP-4. Discussion will proceed on the mailing list to resolve
- this.
-
- The BGP-4 MIB was discussed. The changes required from the BGP3 MIB
- appear to be minimal.
-
- IP Over Large Public Data Networks Working Group (IPLPDN)
-
- The IPLPDN Working Group discussed Frame Relay <=> ATM inter-working and
- offered input to the IP over ATM Working Group.
-
- They discussed ``Shortcut Routing'' document. A revised version of the
- Internet Draft will be produced.
-
- The Group discussed the ``Directed ARP'' draft. After discussing the
- draft the Group agreed to submit the draft for Proposed Standard.
-
- The Group discussed IP over Circuit ID proposal and agreed on a
- framework for an approach. An Internet Draft will be released for
- review.
-
- Also discussed was PPP parameter negotiation over Large Public Data
-

-
- Networks. The Group agreed on a general approach and will release a
- draft for review.
-
- Inter-Domain Policy Routing Working Group (IDPR)
-
- The Group discussed the status of the ``gated'' version of IDPR. The
- software is available form Robert Woodburn (woody@sparta.com) at SAIC.
- There are still things to modify and add, but the software in generally
- in good shape.
-
- The Group also solicited help and received volunteer commitments for the
- following tasks:
-
-
- o DNS Support for address/domain translation.
- o MIB document update and implementation.
- o Configuration Guide Update.
- o Ongoing IDPR ``gated'' support.
-
-
- In addition, the Group introduced and discussed several topics for IDPR
- enhancements. These include:
-
-
- o Super domains.
- o Multicast.
- o Resource Allocation.
- o Dynamic Source Policies for Hosts.
-
-
- The Working Group also conducted a demo of the IDPR ``gated'' version.
- The Group also held a joint meeting with the NIMROD Group.
-
- Mobile IP Working Group (MOBILEIP)
-
- The Mobile IP Group met as a real Working Group for the first time. The
- first of two sessions consisted of presentations of three alternative
- proposals for handling mobile IP hosts by Charlie Perkins of IBM, John
- Ioannidis of Columbia University, and Fumio Teraoka of the Sony Computer
- Sciences Lab.
-
- The second session reviewed and approved the Groups Charter. They added
- to the Charter a mention of the need to consider security and
- authentication issues related to IP mobility. Andrew Maffei gave a
- short talk on the problems of internetworking among ocean going vessels,
- buoys, submarines, and seabed devices.
-
- Steve Deering identified a number of similarities and differences among
- the three proposed mobile host protocols and urged the Group to
- distinguish between fundamental difference vs. ``engineering
- trade-off's'' and to look for ways to combine the best features of each
- proposal.

-
-
- Dave Kumpf described his experience with implementing the Columbia
- Mobile Host protocol and the Group reviewed and discussed a written
- critique of the protocol by Andrew Myles.
-
- Multicast Extensions to OSPF Working Group (MOSPF)
-
- The main topic discussed was interoperation of MOSPF with the Distance
- Vector Multicast Routing Protocol (DVMRP) which is being used to support
- the IETF audiocast.
-
- John Moy reported on his experience with deploying MOSPF in some of the
- OARnet routers in preparation for the audiocast. He found a few
- unanticipated problems with mixing multicast capable and non-multicast
- capable routers in the same OSPF domain. This will be noted in the
- protocol specification. He also re-discovered the need for some
- ``glue'' protocol between MOSPF and DVMRP.
-
- Steve Deering described DVMRP and the subset of DVMRP currently
- implemented in the ``mrouted'' routing demon for Unix. The two major
- shortcomings of the current implementation are:
-
-
- 1. The use of source-routing rather than encapsulation for multicast
- tunnels.
- 2. The lack of multicast tree pruning.
-
-
- The Working Group will submit the MOSPF draft as a Proposed Standard
- after some minor editorial work by John Moy.
-
- Open Shortest Path First IGP Working Group (OSPF)
-
- The Group reviewed four documents that will soon be ready for
- publication before the next IETF. These are:
-
-
- 1. Update to the OSPF V2 Specification.
- 2. Update to the OSPF MIB.
- 3. OSPF Trap MIB.
- 4. OSPF Not So Stubby Area (NSSA) Option.
-
-
- They also discussed two different ways of running OSPF over Frame Relay.
- Frame relay poses some special problems since it is a non-broadcast
- network that is generally not fully mush connected. Approaches to
- gracefully deal with OSPF database overflow was also discussed.
-
- RIP Version II Working Group (RIPV2)
-
- The Group made minor editorial changes to the RIP-2 Internet Draft.
- They also made one type change to the RIP-2 MIB Internet Draft. This is
- awaiting approval from the network management directorate.

-
-
- The Group plans to submit the RIP-2 Internet Drafts for inclusion in the
- standards track.
