Looks like the 45k mark was reached:

I would like to note, that at 45,000+ prefixes even with prefix length filters dropping that down to 37,000 prefixes a 16Meg cisco router can no longer hold a reasonable table. It might be ok if people ran flap dampening at their boarders, but with several flaps per second per provider, and the extra memory and cpu used by dampening and filter-lists, those old 68030s can't cut it. For those people that still have "full routes" going into 2500 series routers, i.e. smaller dual attached providers, you'd better keep an eye out for your BGP sessions to start randomly dropping as you run out of memory. (Oh and if this happens enough Sprint and Digex will dampen your prefixes, and possible others...) --- Jeremy Porter, Freeside Communications, Inc. jerry@fc.net PO BOX 80315 Austin, Tx 78708 | 1-800-968-8750 | 512-458-9810 http://www.fc.net
