We have a bunch 6509s acting as core routers and a bunch of 7204VXRs

Problem Is : I am concerned about performance issues. Is uRPF a big consumer
of CPU / Memory ?
On 6500, I believe the older sup2 has half the routing table capacity
with uRPF enabled, but it's otherwise done in hardware.
6500/sup720 uRPF is "free". There's no CPU/memory load.
I don't know about the other platforms but I would be surprised if uRPF
significantly affects their forwarding performance.
