> 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.
