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.
