At the RIPE conference the was a talk about how MAC addresses starting with a 4or 6 may suffer from decreased performance because MPLS routers misinterpret the Ethernet packets as an IPv4/6 packet when load balancing over multiple links.
One workaround would be to insert additional fields to prevent misinterpretation of the packets. Control words do the trick. Now, I know that control words are enabled on l2vpn connections on juniper by default, but I can't find any information regarding VPLS.
Does anyone know if control words are sent when using VPLS on juniper by default or if we can enable them?
