Okay, so let's talk functionality.
Are there HSSI PCI cards available? Can you do SMDS over this card? Frame? What about a DS3 ATM card, or higher?
And Paul Traina wrote something vaguely similar. I think you guys are both missing what I think was Jon's original point: Routers forward packets faster than PCs, but the forwarding function and the routing protocol function do not have to reside on the same box. You can add a PC (workstation, whatever) which runs the routing protocol and stuffs routes into the router. It doesn't have to support the link-layer du jour. Ethernet will do the job just fine. As I recall the original discussion was of colocating a router, to forward packets, with a workstation, to compute routes. --John

So what would the normal implementation of such a design be? ebgp-multihop all of your peers into the PC, and then a single peering session the Cisco, presuming no "next-hop-self" routes? I can see some amount of value in such a design, if it could be made to work correctly. Does anybody have the spare equipment to build a lab?

But did anybody see real realisation of this?

This is effectively the way we do ISDN PRI backup -- the BGP host isn't (necessarily) in the same router that is actually switching the traffic. So it does work, yes. (This is all with Ciscos, BTW.) Yes, PCs and other workstations can route traffic too. We know that. But as has been noted, this has little or nothing to with with the I-D, and probably nothing to do with the CIDR FAQ either. It would be very beneficial if everybody tried to stay on track. -- ====== ___ === Per G.

Sorry, what's the original question? really, we have a great experience with gated and PC based routers there...
