CURRENT_MEETING_REPORT_ Reported by Ralph Droms/Bucknell University The meeting began with a report from Russ Hobby describing address allocation in PPP. The DHC WG concluded that there's not much overlap between PPP and DHC. Next, Mark Rosenstein reviewed the Gateway Discovery WG meeting. The DHC WG decided that a DHC mechanism could pass an initial gateway without interfering with gateway discovery, with the proviso that any information from a gateway discovery protocol should override any DHC gateway information. The WG agreed to concentrate on the following configuration information: o IP address o Dynamic address allocation bounds o Subnet mask o Network broadcast address o Initial gateway o Subnet MTU The WG further agreed to use bootp as a strawman protocol, with extensions for dynamic address allocation. The choice of bootp is intended to maximize compatibility with existing bootp clients and routers. There are several specific issues that must be resolved if bootp is used as the DHC protocol: o Is the bootp 576 byte packet limit a problem o How to select and negotiate dynamically allocated IP addresses o How should a host proceed when no bootp servers respond o How can a host detect when its environment has changed and 'cached hints' (e.g., a locally recorded IP address) are no longer valid The WG agreed *not* to consider: o Dynamic DNS registration (we refer the problem to the DNS WG) o Higher level configuration information; e.g., network file servers, boot image name o Authentication (we refer the problem to the Authentication WG) What's next: o The WG would like to have a design complete by 9/1/90 o The WG should develop a detailed strawman protocol based on bootp by next meeting. 1 ATTENDEES Basch, Richard probe@mit.edu Bowers, Karen L. kbowers@nri.reston.va.us Broersma, Ron ron@nosc.mil Hobby, Russ rdhobby@ucdavis.edu Jacoby, Ronald rj@sgi.com Johnson, Brad bradcj@osf.org Lauck, Tony lauck@dsmail.dec.com Mamakos, Louis A. louie@trantor.umd.edu McLaughlin, Leo J. ljm@twg.com Minshall, Greg minshall@kinetics.kinetics.com Petry, Michael petry@trantor.umd.edu Rosenstein, Mark mar@athena.mit.edu Roubicek, Karen roubicek@nnsc.nsf.net Seaver, Tim tas@mcnc.org Sklower, Keith L. sklower@okeeffe.berkeley.edu Stahl, Mary stahl@nisc.sri.com Throop, Dean throop@dg-rtp.dg.com VanBokkelen, James jbvb@ftp.com Veizades, John veizades@apple.com Yuan, Aileen aileen@gateway.mitre.org 2
