- 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, ... randy
