1. Set IP options. A pair of Cat 6509Es using VSS can forward packets without options at up to 770 mpps, but when packets have options the maximum is more like 20 kpps. And that's a "high-speed" example; the options forwarding rate is more like 0 pps with some other devices. Silicon that forwards packets very fast is only good when header lengths are fixed.
So what you're saying is "send the right crafted packets and DoS the internet", right? (I think I know which options may make routers go all software-path on the packets but I haven't given it a run on a Cat6500. Hm, I wonder if this here 3750 in the lab will do..) Adrian
