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.
