It gets more interesting if you try to really help your users with
an anycast gateway address. How do you propagate this one, and not
the routers', with RAs?

(Still, for workstation networks, DHCPv6 doesn't seem to really work
and RA is the "builtin" solution)


But basically, I believe the discussion comes from two very different
standpoints/outlooks, and while Benedikt is right in hammering into
our brains that "normal admins" will have to use the whole crap, I
want to remind you guys that this list is for the clueful (aren't we
all?)...
