Re: IXP hardware

Title: RE: IXP hardware
Andrew,

how do you think that the wan leased lines from the telco are going to terminated if you do not use the wan type interfaces? no dsl lines are available in mz at the moment. Well running the wireless point to point solution is possible and one the isps is going to do that. the prob is officially only the university, UEM, is authorized to use the ISM band in MZ so other wireless solutions would need a license. The wireless solution of course will terminate in the switch. The rationale for the suggestion proposed by Antonio is the fact that we could terminate all the links into one single router, but, apart from  Juniper routers that can run multiple ASN processes in one router, i do not know if cisco can do that, one possible solution would be to do bgp multihop. Please contribute if that would be a feasible solution for the IX, advise in regard to performance, reliability, redundancy, etc.

rgds, a./

Probably would be better to have them invest in an ethernet switch proper. The IXC itself shouldn't require any WAN type interfaces. Only the routers that are owned by the ISPs need to have WAN access. So something like a cisco 6000 or Foundry Fastxxxx. Hell, if it's just a few people and you don't think you will need anything fancy just use any ethernet switch with a few ports on it. Really, it depends on how many people and how much traffic you visualize being passed through this. Best bet is to start small but functional using as much of the present resources you have. Its easy to scale it because you just put in a bigger/layer3 switch if you eventually need it.

Regards,
Andrew

Hi,

Thanks guys.
That's just what I needed to know. I guess it would be each ISP's
responsability to bring their router to the IXP. I was also thinking of a
contribution from all ISP's involved to buy a single router with multiple
Serial and ethernet interfaces where they would all connect, something
like a cisco 7200 series. How does that sound?

Cheers,
