MAC learning was broken on X6704 but seems to work with X6908. Forwarding seems to break everywhere when the traffic has to go over the VSL.

Can you access the running TAC case? I have a whole bunch of configs, diagrams and tests documented under case 625216197. If you can't then please let me know and I'll send them to you.

Thanks,
Sander
