Routing Area Director(s): o Bob Hinden: hinden@bbn.com Area Summary reported by Bob Hinden/BBN There continued to be a lot of routing related activities at the Santa Fe IETF. Two talks were given on inter-domain routing. One which represents the work of the IDPR Working Group titled ``Inter-Domain Policy Routing'' was presented by Martha Steenstrup. The other talk described an approach which combines features of IETF Inter-Domain Policy Routing Protocol (IDPR) and the ISO Inter-Domain Routing Protocol (IDRP). This talk was titled ``A Unified Approach to Inter-Domain Routing'' was presented by Deborah Estrin. Seven routing working groups met and there were three routing related BOF's. Their reports are as follows: Border Gateway (bgp), Chair - Yakov Rekhter The Group discussed subnet mask support in BGP. Issues of advertising subnet and supernet masks between autonomous systems were discussed. The discussion evolved into the need to develop an overall internet routing architecture. This lead into the formation of a group which evolved into the ROAD Group. The BGP Group discussed the Internet Draft of describing OSPF and BGP interactions, with the OSPF Working Group. IP Over Large Public Data Networks Working Group, (iplpdn) Chair - George Clapp The IPLPDN Group agreed on bridging formats and protocol identification on IEEE 802.6 LAN's. The Group will forward its recommendations to the IEEE 802.6 committee. This was done in response to a request from 802.6. Protocol identification and encapsulation for circuit ISDN (B channels) were discussed with members of the Point-to-Point Protocol Extensions Working Group. The Group agreed to use the XID procedure to determine the encapsulation format. A code point will be obtained to indicate PPP in ISDN. The Group will document this in an Internet Draft. An Internet Draft updating IP over X.25 was discussed. The comments will be incorporated in a new version of the document. There was a long discussion on how routing should work over large public data networks. Proposals for ``Directed ARP'' and ``Short Cut'' routing were discussed. One of the major issues is whether there will be different IP network addresses on each public network or if there will 1 be one (i.e., class A) network number for each network. In the former case should traffic be required to go through a router. The Group decided to recommend to the IESG that the ``IP over SMDS'' RFC be advanced to Draft Standard. IP Routing for Wireless/Mobile Hosts (moblhost), Chair - Steve Deering The Group met and was well attended. Dan Duchamp gave a presentation on the work done at Colombia University to support roaming wireless IP Hosts. Ken Carlberg described his work at SAIC on connectionless ISO CLNP support for mobile end systems. Steve Deering reported on the current work of the IEEE 802.11 Wireless LAN committee. The attendees agreed there was enough interest to form a working group. Steve Deering will Chair the Group and write a Charter. IS-IS for IP Internets (isis), Chair - Ross Callon The Group met and updated the RFC for Dual IS-IS to be compatible with the current international standard for IS-IS. An Internet Draft reflecting these changes will be produced soon. The Group also discussed the IS-IS MIB. An Internet Draft is now available. Work was started on BGP-ISIS interactions. The approach taken is similar to what has been done with OSPF and BGP. Inter Domain Policy Routing (idpr), Chair - Martha Steenstrup The Group reviewed the current Internet Drafts describing the IDPR protocol. They also discussed how IDPR would be used in the Internet and how it interacts with existing routing protocols. The Group also reviewed the status of the IDPR ``gated'' implementation. The Group met jointly with the Router Requirements Working Group. The goal was to make sure that IDPR was not inconsistent with the router requirements specification. The result of the discussion was that there were not any inconsistencies. Multicast Extensions to OSPF (mospf), Chair - Steve Deering The Group completed reviewing the first draft of MOSPF specification (60+ pages). The main concerns raised were in the area of inter-autonomous system interactions and co-existence of multiple multicast routing protocols in the same router. An implementation of MOSPF is underway at Proteon and a ``gated'' implementation is planned by Cornell. New Internet Routing and Addressing Architecture (nimrod), Chair - Noel Chiappa The BOF discussed Noel Chiappa's proposal for a new internet routing and addressing architecture. The first half of the meeting was spent 2 reviewing the proposal and the last half was spent getting a better understanding of the overall dimensions of the architecture. There was general interest in forming a working group. Open Shortest Path First IGP (ospf), Chair - John Moy The Group discussed the ``Virtual Link'' problem found during multi-vendor OSPF interoperability testing in Foxborough, MA. A backward compatible fix has been developed. The OSPF specification is being updated to reflect the fix. The Group reviewed a set of changes to the OSPF MIB and the new OSPF Trap MIB. The later will be published as an Internet Draft. Work continued on the proposal for an new OSPF option ``Not So Stubby Area''. This option will provide for improved support for RIP clouds attached to OSPF domains and help with the transition of domains from RIP to OSPF. This option is now fully fleshed out. The Group also discussed the possibility of defining a reduced subset of OSPF for autonomous systems not needing the full functionality, such as stub domains. RIP Version 2 BOF (ripv2), Chair - Gary Malkin A BOF was held to see if there was sufficient interest to form a working group to develop a new version of RIP. Features to be added to the protocol included: o Subnet Masks o Authentication o Autonomous System Numbers o MTU & Link Speed indications The attendees agreed that a working group should be formed. 3
