Some problems never go away, just reappear periodically -- strict uRPF (and even loose uRPF) on transit provider peering interfaces are going to have unintended consequences as long as their is routing asymmetry

I can't imagine why uRPF/loose would be problematic. If you're originating traffic from prefix which you're not advertising to DFZ and you still expect it to work, your expectation are at fault, not uRPF/loose. However uRPF/strict feasible won't work, while occasionally some people seem to think it does. -- ++ytti
