That pattern is meant to match exchange names - is that how your 
exchanges are named?

That should be the case. My guess is that the policy is not matching any 
exchanges and so federation thinks it has nothing to do. Do you see 
"federate-me" show up in the management UI exchange list / "rabbitmqctl 
list_exchanges name policy"?
