Ok, so you could not use a proxy server unless you Ogot some other NSP to set up a server also? Is this correct? I want to set up a MAE-East connection, I have a 4000 and only 16 megs or ram. Would I be able to set up a PC as a route server and not need 64 megs or ram in my router? Tue, 15 Aug 1995, Nicolas Williams wrote:

As I recall the original discussion was of colocating a router, to forward packets, with a workstation, to compute routes.
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?
No. Colocated BGP4 "proxies" (I'm still not sure what to call these, anyone?) would peer via EBGP with other ASes BGP4 "proxies" on the same net. The next_hop BGP4 attribute on all routes exchanged would be that of the routers on the high speed interconnect, not of the "proxies." ASes that do not implement this would still peer via EBGP router-to-router as usual and would not see the "proxies;" eventually everyone would move towards having "proxies" or else router vendors would beef up their products, either way, we're all happy.
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? (pfeh, yeah, right)
It would work (see the comment on the next_hop BGP4 attribute above).
I'm sure there are folk out there that would be willing to experiment, all you need is for two ASes to try it at some exchange (and permission by the exchange to run the necessary ethernet).
