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hints' (e.g., a locally recorded IP address) are no longer valid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.
