Hi all, Talking about a small local ISP we helped put together, we used some relatively low-end pc's running OpenBSD+OpenBGPd on flashdist (openbsd read-only on DiskOnModule flash disk). This was about 3 years ago. The machine has a Celeron 2.4Ghz and 512Mb of RAM, and today, getting full routes from two upstreams, the machine is using 181Mb of RAM and itself routing about 300mbit/s of traffic ... Try this with a three years old Cisco for less than CHF 2000.-- This hardware has been running flawlessly since beginning ... I wouldn't recommend this setup for ultra-large networks (well ... why not ...). I mean as core BGP routers, why not, but probably not as edge. If you are getting close to fulling your available memory on your Cisco, you should try "offloading" the BGP work to a software router ... you can get quad core pc's with 4Gb of RAM and pci-express gbit for less than CHF 2000 ... buy two of them if you are worried ... we have the real world example ... it WORKS ! It is even getting easier today, have a look at Vyatta : http://www.vyatta.com/ or http://www.imagestream.com/, or try it yourself using OpenBGPd (highly recommended), Quagga or Xorp. _______________________________________________ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
