One of the areas in which the guidelines draft already discusses the problem (a bit) is DHCP packet sizes. That's more for guiding what to do with large payloads (use TFTP or HTTP or etc) so far. Several drafts have an almost 'boilerplate' description of RFC3396 behaviour, including the RFC3396 behaviour in their examples. We've gone back and forth on this with authors a few times, where the re-description of RFC3396 is incomplete or misleading. It ocurrs to me that anything beneath the new option's payload is "DHCP Protocol". So the thought I've recently had is our common practice of including the Code and Length bytes (or words in DHCPv6's case) is maybe the real source of the problem. It seems simpler, on the surface, to document only what code has been assigned (external to any ASCII art), specify any fixed lengths of the payload, and then the specific payload contents. This creates a rather sudden and jarring inconsistency in existing option specifications, however. Or alternatively we could strive to make a single boilerplate. -- Ash bugud-gul durbatuluk agh burzum-ishi krimpatul. -- David W.
