Just curious, do most vendors' hardware need to hit the cpu when doing policy-based routing?
As far as I know, the hardware that you are likely using from the major company in the bay area is going to put all PBR traffic through the CPU. Other vendors do it in different ways, but any vendor that only does the standard destination address lookup in hardware will have to do exception processing in the CPU. Most routers fall into this category. The differences will be how efficiently the CPU handles the processing, and that will determine the load. Unfortunately, any more specific information of what vendors do would be a violation of the NDAs. -Sean
