- public IP addresses for ipv4 and ipv6
- requirement for all members to use BGP, their own ASN and their own 
  address space

just to not confuse, that is behind the peering port.  the peering port
uses the exchange's ipv4/6 space

- no customer IGPs
- dropping customer bpdus on sight
- ruthless and utterly fascist enforcement of one mac address per
  port, using either L2 ACLs or else mac address counting, with no
  exceptions for any reason, ever.  This is probably the single more
  important stability / security enforcement mechanism for any IXP.

You should also take a look at the technical requirements on some of
the larger european IXP web sites (linx / ams-ix / decix / etc), to
see what they allow and don't allow.

sharlon, reread nick's advice a few times, maybe pin it to your wall.

It goes without saying that you're not going to be able to do this on
your average low-end switch.

just curious.  has anyone tried arista for smallish exchanges, before
jumping off the cliff into debugging extreme, foundry, ...
