OTOH, I know of other ISPs also present on the AMS-IX that have
been using Extreme switches to connect to the AMS-IX and their
upstreams without any of those problems. Their network has been
very stable for over a year now, I think. It's even a fault-tolerant
setup with VRRP.

Cistron IP is using a Foundry switch right now as core router.
You can't get a BGP/OSPF router with lots of GigE and 10/100
interfaces for that price over at C or J ..

We had some problems with instability at first, but with recent
firmware everything runs just fine.

We have several full BGP upstreams and over a hundred of AMS-IX
peers (at GigE) and it works fine.

On of the nicest things is that the box boots in 15 seconds or
so and even with >100 BGP sessions coming up simultaneously
it's still fast - a Cisco would take minutes to get all BGP
sessions up, the Foundry does it in mere seconds.
