Re: NAP/ISP Saturation WAS: Re: Exchanges that matter...
Yes, the cisco needs more backplane, but the CPU cant keep up. Have you not watched a cisco meltdown when you lose a few NAP connections. Yes if you do not want to run a lot of BGP, have small OSPF tables, and don't want to do a lot of filtering then the 7500 is fine. The CPU can't keep up because of the caching (which should have died by now) and because the same CPU is used for switching. I believe that there is a knob that guarantees that non-switching functionality get a guaranteed percentage of the CPU. I strongly suggest you try it out. Get the switching out of the way, and the box would be much happier. Get the cache out of the way (a software only fix) and the box becomes much more useful. Tony - - - - - - - - - - - - - - - - -
