Room:	Crystal Ballroom A-C
Presenters:	Speakers: Job Snijders, Atrato IP Networks Job Snijders is a Senior Networker at Atrato IP Networks (AS 5580), one of the largest backbones in Europe. Job develops high-end networks and provides advise on everything for which the network is an integral part. Job has regularly taught IPv6 at MENOG workshops in the Middle East. He is actively involved in the the global operator community through the NLNOG RING, the RIPE Program Committee and has helped develop the LISP protocol within the IETF. Jeff Wheeler, Inconcepts.
Abstract:	MPLS P routers have trouble dealing with ethernet frames destined for a MAC address starting with a 4 or a 6. Isn't that absolutely fabulous? MAC addresses starting with a 4 or a 6 are not treated as equal citizens! Symptoms you might encounter when dealing with a L2 pseudo-wire or a L3VPN service include re-ordering, congested links or plain dropping of frames. Are you using remote peering? Is your enterprise relying on an out-sourced L3 backbone? Do you extend VLANs from one datacenter to another? YOU MIGHT BE AT RISK. A well-kept secret of router vendors, we illustrate this problem so the common operator can fully understand what is happening, why, and some thoughts on how to mitigate and fix it.
