Good suggestions all, but as a short-term solution access lists work. A Cisco 7500 with an access list 30 pages long (literally -- I printed it out once) works on an OC48. Not sure how that would stand up to a couple truly massive floods, but it works fine under normal traffic and the average flooding any ISP gets.
Yeah, but the challenge is getting an OC48 into a 7500. ;) And frankly, I've -never- seen a significant[0] access list perform well on an RSP4 at even OC3 level. Then again, the last time I tried such a thing I wouldn't touch CEF with a 10-foot pole. Maybe it's better now. -c [0] significant = longer than about 5 lines, even with 'permit tcp estab' as the first line
