That would seem to be the logical outcome, yes.
Like I said before, that would pollute the network with many multicasts which can seriously degrade wifi performance.
Regardless of it's potential downsides, the issue at hand was the RFC compliance of such a setup. Owen DeLong contended that: On Fri, Jun 10, 2011 at 09:12:26PM -0700, Owen DeLong wrote:
As it currently stands, an RFC-compliant host will not attempt to solicit a DHCP response unless it receives an RA with the M inclusive-or O bits set.
Daniel was merely requesting a reference for that assertion. If you have one, I'm sure Daniel (and Owen) would appreciate it. - Matt
