you know what I love? address selection rules, or rather the fact that we have to have them in this new ip protocol :( bugs and code problems and operational headaches and filters and ... :( On Fri, Apr 27, 2012 at 12:31 PM, Jack Bates <jbates@brightok.net> wrote:

More specifics rule out over connected any day.
That would also kill any legitimate link-local traffic though.
Perhaps. I'm actually curious on that, as the rules for routing to link-local are very specialized. It might flag on uRPF for local traffic, but that can be overcome with a fail filter. Sending out from the RE could likely ignore the route, as it has to send to specific interfaces. Receiving on interfaces that don't have uRPF should still work as well.
It's a theory and would have to be tested.
