We've had a couple of NPE-G1's/G2's and we run both loose 
and strict mode uRPF on all customer-facing interfaces. 
Works like a charm.

We have an NPE-G2 running close to 500Mbps @ 64% CPU 
utilization. All traffic to/from this box goes through tons 
of uRPF-enabled interfaces. No major drama.

IOS 12.2(33)SRC5.

Cheers,

Mark.
