No exchanges or queues get created when messages are sent.

Your exchange.federate exchange will get created on the upstream when 
the downstream exchange is created. That's just for convenience; there 
is nothing stopping you creating the upstream exchange explicitly before 
hand.

With the setup as you have it, a message published to the 
exchange.federate upstream (i.e. on your Cluster1) will get routed to 
the downstream (your Cluster2) and end up in your queue.federate queue.
