CURRENT_MEETING_REPORT_ Reported by Kim Long/NYSERNet and Susan Hares/Merit Minutes of the Joint Session of the BGP and IPIDRP Working Groups BGP Status A presentation on the status of BGP was given by Yakov Rekhter. The documentation is complete, and the working group is waiting for the IESG to approve the documents for publication as Proposed Standards. The BGP-4 protocol specification needs one minor fix and will then be submitted to the RFC Editor. IDRP Status A commercial version of IDRP is available from TELEBIT. o IBM Implementation Dave Jacobson gave a presentation on the IBM implementation of IDRP. It is a stand-alone implementation which allows integrated IP and ISO routing, and can be sent over IP or CLNP; it works with gated. The coding phase is largely completed, and they are in the process of doing unit testing. Four to six nodes have been tested. The second stage will be a hardware system test. The basic transport, internal/external redistribution, preference and distributed policy, and kernel interface for the IP layer have been implemented. o Merit IDRP in Gated The Merit implementation was presented by Sue Hares. Merit implemented with OSI and IP. The debugging is all done on Unix (BSD 4.3+ (4.4 ISO code)). It was implemented on the 3.02 gated release. They will move to gated 3.5 and gated 4.0 after release 1.0. They are tracking gated work. - There is no policy base. It will have mandatory attributes plus DIST_LIST_INCL, DIST_LIST_EXCL, NEXT_HOP, EXT_INFO, MULTI_EXIT_DISC; attributes will be ready by 20 April. - IDRP base and policy, and FAA auto configure bis will be ready in May 1994. Aggregation and RDC support may come in the summer of 1994. - QOS attributes will be supported. Work is starting now, with final delivery in November 1994. QOS requires multiple RIBs in gated, QOS support in kernel, and IDRP changes. - There is still no kernel for the SIPP work. Intra-Domain Route Server The goal of the intra-domain route server was to provide an alternative to IBGP/IDRP full mesh. Dimitry Haskins's proposal tried to reduce the number of IBGP connections without relying on IGP support to carry BGP/IDRP routing information (e.g., without using OSPF or IS-IS flooding). Each BGP does not have to have a full routing table. The BGP queries the route server when the first selection is no longer valid. Many questions were raised regarding the implementation and architecture of the server. The draft needs some clarification. During the discussion, Tony Li presented an idea like Dimitry's with ``routing cliques.'' Tony described a route server which has a hierarchical distribution of network announcements called cliques. Each clique has a subset of routing information. It was suggested to restructure the current Internet-Draft into two documents---the first will cover just the route server, and the second will address the ``route fetch on demand'' capabilities. It was also suggested to replace the term ``route server'' in the first document with something else. The working group agreed that it would be highly useful to enable OSPF and IS-IS flooding mechanisms to be used for flooding BGP/IDRP routing information within a domain. The BGP Working Group Chair, Yakov Rekhter, agreed to pass this information on to both the OSPF and IS-IS Working Groups' Chairs for consideration and appropriate actions. Route Dampening (ANS) Curtis Villamizar presented a summary of his draft proposal on how to weight timer values to dampen out the route flaps. This is done by introducing a timer structure per route received from a peer, based upon a timer and some state history. No measurements were done and no statistics are available. CIDR impact might address loss of AS. The working group agreed that it is worth while to pursue the work further, but there is a need for more empirical data to see whether it should be recommended for implementation or not. Issues with Using TCP in BGP Geoff Huston noted that a replay of TCP RST (reset) could cause problems with BGP. Such replays may result in terminating BGP sessions (due to the termination of the underlying TCP connection), which in turn would cause routing instabilities. BGP Future Paul Traina suggested that any future work on BGP-4 be limited to bug fixes, with the rest of the activities (including any new features) being refocused on IDRP. ROLC Joint Meeting In the ROLC joint meeting, two items were discussed: ARP servers and Curtis Villamizar's Internet-Draft on the NBMA BGP attribute.
