We run both Strict and Loose mode uRPF on all our routers, without
issue. Our Internet leaves in the default table, and we've never had a
uRPF issue.

I would not have foreseen a problem like the one Niall has faced, if I
were to run the Internet in a VRF. I would not have even considered it
to be a potential issue. But because of all the unknowns previously
documented with limitations when the Internet is in a VRF, as well as
what we don't already know as software continues to bloat, I simply stay
away from it. I am not suffering anything by not having our Internet in
a VRF.

It's like Broadcom chipsets on IP/MPLS routers... it's getting better
with each iteration of the silicon, but there is always a niggle you
may, or not may know about.
