[AusNOG] 20G+ Routing on the cheap

[Tony]

You're unlikely to get Cisco 6k for that price. The 10G modules alone are going for $12k+ on ebay (ie. just the card, no chassis or other suff you need). If you do go this path, remember that you need the 3CXL to hold 1 million routes. The normal 3C are only good for 256k routes. The new SUP-2T for Cisco 6500 has 2x 10G ports on the SUP (still out of your price range, but provide a reasonable solution if you only need 2x 10G ports).


Do you need 10G of transit ? Is it possible to instead bond a few 1G ports to together to get perhaps 2-4G of transit and then you could do it on a device that has "only" 1G ports which would be a lot easier to find within your budget ? I realise this does limit you maximum capacity to how many ports you can bond together (ie. probably 4G max), but if you buy something that is modular (ie. Cisco 6k) the 10G ports should be a lot more affordable in a couple of years time if you don't need that much transit right now and you can upgrade at that point in time.


I don't have much experience with 10G cards on Linux, is it able to route that much traffic  (ie. raw device throughput) ?



regards,
Tony.

The problem is the full routing table AND the ports, there really just doesn't exist such a product (yet), unless you are really really lucky to get something 2nd-hand like a 6k with the 10G modules as part of the deal.
