Yes - see the section on "Federating clusters" in http://www.rabbitmq.com/federation.html. From the documentation on http://www.rabbitmq.com/federated-exchanges.html you might also want to look at the section "Can I federate a federated exchange?" as well.

You can use the "nodes" policy to deliberately change which nodes are mirror-queue masters. The key thing usually considers though, is how many slave nodes you want to replicate across. But in general, yes, you can (and will) have master queue processes residing on various nodes in the cluster.

TTL does not continue during downtime.
