----------------------------------------
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.
