SV: 10gbps peering subscriber switch recommendation

[andreas.larsen at ip-only.se (Andreas Larsen)]

Xtreme x480 can do this and has upto 6 * 10G ports. 
It can actually hold a full bgp table also and is preatty cheap.

?mne: 10gbps peering subscriber switch recommendation

Good morning,
We're in the market to move our IX peering off of our core (too much BGP/CPU :-/ ) and onto a dedicated switch.

Anybody have a recommendation on a switch that can do the following without costing a fortune? I have scoured Cisco, and bang for the buck is ... ASR9k (way over powered for handling zero-feature IX traffic),

3-8x 10gbps ports
64k routes minimum, preferably 128k
Must be able to speak BGP
Native/functional IPv6 would be sharp!
Basic QoS to police our ports

The prefix count seems to be the killer, as our exchange table is getting pretty big (42k+ currently). I'm really tempted to build a vyatta box or similar, but would rather do something off the shelf -- especially if it can be 1-2 gens old and cost effective.

I'm certain that this same situation is scratching many other folks as exchanges become more important.

Thanks for your input in advance -- stay warm!
Randal
