However, there's still a market for those "Internet access toasters" that are basically PC's plus T1 interfaces, for the "set and forget" crowd. The cost issue, however, not true for BGP routers. Despite the dot-bombs the 7204/6 and the 3640 (both minimum cost of entry for BGP4 on Cisco) are both still very expensive even on Ebay. It's still cheaper to hook a fast Celery or something like that to an ISP feed. Furthermore, I feel compelled to point out that the Internet is still getting bigger and bigger and bigger. At some point in time even with Cisco's packing algorithims, the BGP route table plus Cisco IOS will exceed 128MB of ram. (both the 7206 and 3640 are limited to this as a maximum) Long before that the CPU's used in those Cisco devices will be swamped. And, I hear your answer to that, but screw that, why should I have to settle for a half-assed BGP feed with 3/4's of the routes chopped out of it from my providers? I've run BGP4 into both 7206's with NPE200's and Pentium 500Mhz systems with WANic cards, and the PC will converge BGP views faster than the Cisco, and tolerate route flaps far better, while under routing load. Cisco has a lot of exposure here, and their answer to the need for increased routing power on the Internet has been routers costing in the $100,000 range. Now, maybe BEST Internet is now wealthy enough that you can blow that kind of money on Cisco gear without thinking about it, but a lot of smaller ISP's are not. If you look at what happened last weekend on Sunday, and the number of people that screamed about it, it's quite obvious that there are a huge number of gated and zebra boxes out there handling global routing. Take off those Cisco blinders, boy! ;-) Ted Mittelstaedt tedm@toybox.placo.com Author of: The FreeBSD Corporate Networker's Guide Book website: http://www.freebsd-corp-net-guide.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
