CURRENT_MEETING_REPORT_ Reported by Yakov Rekhter/IBM BGP Minutes Discussion focused on the following subjects: 1. Collision detection in BGP. Yakov Rekhter presented a proposal that allows detection of such a such collision. 2. Third party advertising. Matt Mathis suggested that BGP should be less restrictive with respect to what can be advertised as a next hop. This was also supported by other members of the Working Group (specifically Scott Brim and Jeff Honig). 3. Carrying MAC address of the next hop. Paul Tsuchiya proposed to either replace IP address of the next hop with the MAC address or to carry both IP address and MAC address of the next hop. 4. Abbreviated form of an unreachable route. Yakov Rekhter presented a proposal from Dennis Ferguson (who was not present at the meeting, but posted his proposal to the IWG mailing list) that allows simplification (and shortening) of the announcement of unreachable routes. 5. Sorting path attributes within the UPDATE message. Scott Brim suggested that for efficiency, path attributes within the UPDATE message should be sorted by attribute type. The group agreed with items 1, 2, 4, and 5, but did not feel that carrying MAC address (either in addition or instead of IP address) of the next hop is desirable. The group recommended incorporating changes into RFC1163 to reflect items 1, 2, 4, and 5. Yakov Rekhter agreed to generate modified text of RFC1163 that would include these changes. The modified document will be posted on the IWG mailing list within a week from the meeting. 1 Attendees Scott Brim swb@devvax.tn.cornell.edu Ronald Broersma ron@nosc.mil Dino Farinacci dino@esd.3com.com Vince Fuller vaf@Standford.EDU Jack Hahn hahn@umd5.umd.edu Robert Hinden hinden@bbn.com Jeffrey Honig jch@devvax.tn.cornell.edu Kathleen Huber khuber@bbn.com Dan Jordt danj@cac.washington.edu Christopher Kolb kolb@psi.com E.
