[jira] [Created] (ARTEMIS-4658) AMQP Federation should prevent reflection of multicast messages between nodes

Timothy A. Bish created ARTEMIS-4658:
----------------------------------------

             Summary: AMQP Federation should prevent reflection of multicast messages between nodes
                 Key: ARTEMIS-4658
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-4658
             Project: ActiveMQ Artemis
          Issue Type: Improvement
          Components: AMQP
    Affects Versions: 2.32.0
            Reporter: Timothy A. Bish
            Assignee: Timothy A. Bish
             Fix For: 2.33.0


When using a topology where brokers are dual federating messages for addresses the federation producers and consumers should prevent reflection between the two nodes.  This allows for more complex configuration where the max hops value is insufficient to prevent duplicates and cases of infinite reflection if the user forgets to configure max hops. 

Such a case would be a hub and spoke type setup where the producers and consumers are on each of the spokes and the hub is the way point, here the max hops needs to be set to '2' but this allows for a reflection from the hub back to the sending spoke.
