The problem is that you *could* have local/campuswide ipv6 connectivity,
but not have an IPv6 connection to the outside world.  So my system comes
up, it sees a Router Advertisement, it can get to other IPv6 systems that
are 3-4 hops away.

So how is it supposed to "know" that it doesn't have an ipv6 connection?

Presumably the same way it "knows" it doesn't have an ipv4 connection when
your OC-moby to the outside world falls over, but it's still perfectly able to
talk to the entire rest of your corporate network....
