[j-nsp] uRPF - Performance

[Rob Walton]

Jack,

         We (DANTE) have enabled uRPF right across 90% of our border 
interfaces and we have seen zero performance degradation. Many or our 
access circuits are as high as 10G so i would say that you would have no 
problem with 600Mbps.

         I would recommend you investigate the different implementations 
and understand the differences between strict, feasible path and loose as 
to avoid and unexpected behavior though. ;o)

cheers,
Rob
