JC> Date: Thu, 23 May 2002 15:25:14 -0400 (EDT) JC> From: James Cornman JC> We've had some rather good success with FreeBSD based PC JC> Routers. Typical setup was FreeBSD 4.x, 512mb, 20gb RAID-1, JC> 3com Gigabit Ethernet card, Fore Systems OC3 ATM card. All JC> this, with zebra on top.

Yes, for <= 155 Mbps, it works well. My intended point was that Juniper != PC. Yes, both are FreeBSD on x86, which works great. But PCs use the system bus, which is a much harsher limit than having a fast backplane or midplane that just switches data. As Randy said, a router must route _and_ forward. When PCI runs out of gas, you just can't push any more through it. Again: Anyone played with cPSB yet? It looks very promising... The "sweet spot" for building a PC-based router probably would be around 2x or 3x DS3 right now. 7200s have come down in price, but DS3 cards are still fairly valuable. (Not enough price difference in the DS1 game to make a PC-based router worth the effort on the low end... unless one is multihoming and needs more RAM than 26xx or 36{20|40} can hold.) I'm trying to remember what "Buy It Now" was on that M20 on eBay the other day... IIRC, it had 4x OC3 + 4x DS3 + 4x FE. JC> We did VLAN trunking through the 3com GBE card to a Catalyst JC> 3548. Did any rate limiting with DUMMYNET and ipfw pipes. JC> Overall, the whole system worked great for a few months JC> without human interaction, until the ospfd problems. How long ago was this? Zebra has been stagnant for nearly a year now, and my recollection was that late 2000 was when OSPF bugs were biting... -- Eddy Brotsman & Dreger, Inc. - EverQuick Internet Division Phone: +1 (316) 794-8922 Wichita/(Inter)national Phone: +1 (785) 865-5885 Lawrence ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Date: Mon, 21 May 2001 11:23:58 +0000 (GMT) From: A Trap <blacklist@brics.com> To: blacklist@brics.com Subject: Please ignore this portion of my mail signature.
