My favorite quote from their config guide: 4.2.6. Non-unicast IPv4: IGMP, DHCP, TFTP On the ISP peering LAN, the only non-unicast traffic that is allowed is the ARP query. Sometimes we see equipment trying to get a configuration through broadcast TFTP, or configure themselves through DHCP. We will leave it to the reader to consider why this is a bad idea.

Can we revisit the whole spanning tree on the IX thing again?
My two cents last time was for 1 mac address per participant facing port, proper storm control limts, bpdufilter, etc.
Also, I'd encourage all participants to review their config's, *especially* if they have layer2 devices in the mix somewhere. AMS-IX has put together very nice and self-explainatory guides about how to keep your layer2 devices acting nice and not have a negative effect on the entire MICE IX.
That configuration guide is located here: http://www.ams-ix.net/config-guide

Anyone else have an issue? stats.micemn.net show spikes which would likely indicate a spanning tree loop or a broadcast storm. Whatever the traffic was, it caused a CPU spike and upset all of our other BGP sessions on our ASR as well.
