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. Jack
