Routing Area Director: o Joel Halpern: jhalpern@newbridge.com Area Summary reported by Joel Halpern/Newbridge Networks Corporation Inter-Domain Multicast Routing Working Group (IDMR) There was a description of the planned transition for the MBONE from its current methodology to a hierarchical methodology. It is hoped that the eventual state will use the work of the IDMR Working Group. There was a presentation of the state of the CBT protocol, reflecting a years work on the issues that had been discussed previously. There was a presentation by George Oliva and Chuck Graff from the US Army on the military requirements and intended usage for Internet multicast. Finally, there was a discussion of how to proceed with the two protocols, PIM and CBT, which the group has discussed. The group hopes to arrive at consensus on this issue expeditiously. Inter-Domain Routing Working Group (IDR) The group agreed to the following: o To advance CIDR to Draft Standard. The revised documents and CIDR Experience document will be available by no later than mid January 1995. o To advance BGP-4 to Draft Standard. The revised documents will be available by no later than mid January 1995. o To advance Guidelines for Using AS Numbers to a Proposed Standard. The revised document will be available by no later than mid-January 1995. o That certain modifications are needed to IDRP for IPv6. The editors will produce a revised Internet-Draft to reflect the comments. o To add a new attribute (tentatively called ``Route Color'') to BGP-4. The Internet-Draft documenting the attribute will be available before the next IETF. IP Routing for Wireless/Mobile Hosts Working Group (MOBILEIP) The working group session was very productive. Bud Graff gave a presentation on Battlefield Digitization. The group discussed open issues with the current draft. Rough consensus was reached on all technical details that impact functional correctness of the protocol. The group even reached consensus on most of the secondary issues. Charlie Perkins updated the working group on the status of the IBM patent. Charlie would like a letter from the IESG and the working group saying what ``reasonable terms'' means to the IETF. The editor will incorporate changes from this meeting into the draft and release a revised Internet-Draft. There will be a two week discussion period on the mailing list. If no major technical issues are raised, the group will encourage implementations. New Internet Routing and Addressing Architecture Working Group (NIMROD) The NIMROD Working Group met on 7 December and 8 December. The topics covered were: o Database organization o External data representation o Update protocol o Query/Response protocol o Route setup/tear down protocol o Transition A list of architectural alternatives was identified. These will be discussed on the mailing list. Open Shortest Path First IGP Working Group (OSPF) The OSPF Working Group met for a single session on Wednesday, 7 December. The group discussed Fred Baker and Rob Coltun's ``OSPF for IPv6'' draft. Ran Atkinson led a discussion of MD5 authentication for OSPF, where a number of issues requiring clarification were uncovered. Fred Baker then summarized the changes that have occurred to the OSPF MIB since its last publication (RFC 1253). The ``OSPF over demand circuits'' draft was discussed, with an implementation report given by Dawn Li of 3com and a comparison to the Demand Circuit RIP support given by Gerry Meyer. Finally, the ``OSPF database overflow'' draft was quickly described. RIP Version II Working Group (RIPV2) The RIPv2 Working Group completed all of the items on its agenda. This included making a recommendation that RIP-1 (RFC 1058) be moved to Historic status, discussion of the ``RIP-II Cryptographic Authentication'' Internet-Draft, decision to proceed with RIPng, and discussion of the RIPng Internet-Draft (which will need considerable work prior to the Danvers meeting). The charter for the group will be changed and the group will be renamed the RIP Working Group. Router Requirements Working Group (RREQ) The group reviewed the status of the charter and found that with the publication of RFC 1716, they were near completion. Fred Baker is working on a standards track revision, which includes CIDR and PPP documentation. In support of CIDR, the group recommended that RIPv1 (RFC 1058) be moved to Historic status. Routing Over Large Clouds Working Group (ROLC) There were 108 attendees. The chair presented introductory and background material for the benefit of the newcomers, of which there were many. The working group received an ATM Forum Multiprotocol over ATM report from Drew Perkins and Joel Halpern. Kanan Shah discussed her NHRP implementation status. The group went through a detailed review of the current draft, draft-ietf-rolc-nhrp-03.txt, which had been distributed on the mailing list the previous week. A number of action items for the editors were generated. Three new work items were started: a protocol analysis, an applicability statement, and a MIB. The work plan was updated, and will be reflected in a charter update. Source Demand Routing Working Group (SDR) The current status of SDR was presented. The protocol has been submitted for Experimental status. Vendor implementations are scarce because it is currently difficult to present a clear business case for SDR. ERP was presented. This is the successor to GRE and SDR designed for IPv6. There is an Internet-Draft on this. There are significant open issues remaining. The work on route construction was also presented. One aspect of this is to develop hooks into IDRP for SDR/ERP support. Other approaches include path explorers and Route Information Filters. There is work needed on the interaction between SDR and multicast.
