RE: [69ATTENDEES] DHCP

["Gunter Van de Velde (gvandeve)" <gvandeve@cisco.com>]

My believe is that either 'DHCP' OR 'RA' provides this exclusively and
not by both.
What if a host receives from both an announcement? (we could create
policies etc... however 
policies just complicates these aspects.).

Would central services not be best announced by a central capable
technology?

	Seriously though, I would see it as an unfortunate mistake to
take
	the view that the capabilities of RA and DHCP to provide
configuration
	data should be strictly disjoint.  The important point here is
the
	distinction between 'capability' and actual 'advertisement'.

	If DHCP is a 'natural' means to meet some service requirement,
it may
	be convenient to have it provide configuration data which might
	otherwise be provided by RA.  Implementors should take care to
	provide configuration options for both, as they will be needed
in
	order to allow netadmins the scope they need to exercise their
options
	and avoid conflicting advertisements.
