I have a 6509 using sup 720's. I see a spike in CPU utilization (average spike is 50%) every 10 minutes or so. It is due to my IPX traffic. I can't get rid of the IPX so I was considering moving the routing of it to a stand alone router. I'm not really sure what kind of router I'd have to get because the 720's are pretty fast as it is.
Anyone with any suggestions or think this isn't a good idea?
