[j-nsp] uRPF - Performance

[Jack.W.Parks at alltel.com]

We are looking to enable uRPF on our M-series routers (M20's and below).
The benefits of enabling this feature are obvious, but the unknown side
effects are what I'm concerned about.  What performance impact could I
expect by enabling uRPF at a peak traffic flow of 100k pps/600Mbps?

Has anyone enabled uRPF on their network and do you have any lessoned
learned?  I would like to iron out the quirks prior to deployment.
