Hello folks, I am trying for some time a symmetric configuration without explicit address federation. Seemingly it works until a client failover changes the direction of addressing. Then the address memory in the artemis broker grows despite of the message TTL settings. The broker configuration is a simple cluster connection and probably wrong for the intended purpose. I now think that address federation is what I had been missing. Is this true? The example in the federation documentation is too complex for me, though.
How would address federation for a symmetric or call it ?two broker mesh? for all addresses look like?

The documentation does mention using a "hub and spoke" federation topology [1]. However, as you noted, there's no example configuration. I wonder if this may be down to the "max-hops" setting you're using. Can you provide the broker.xml from your brokers attempting to use hub & spoke?
