I have two brokers (call them A and B), where A establishes a connection to B with the options: duplex="true" networkTTL="3" dynamicOnly="true"
I have two clients connecting to broker A, and one to B. One of the clients on A is subscribing to a queue, the other is publishing to it. The client on B is not using that queue at all. When the publishing client sends a message, the subscriber receives it as expected. But if I watch the network with a sniffer, I can see the message being sent to broker B and back again. I also set up a topic that all of the clients subscribe to. If a client on A sends a message to the topic, the client on B receives it normally, but the two clients on A receive the message twice. I can see with the sniffer that the message is being sent from A to B and back. If I change the connection so that it's not duplex (i.e. I set up matching simplex connections on both brokers) all of this unexpected behavior goes away. In the first example, the messages are no longer forwarded to B since there are no subscribers on that broker. In the second example, the message is received once by every subscriber. Did I misconfigure my duplex connection somehow? I can run it with the two simplex connections for now since I'm in a test environment, but I'm going to need to move to duplex for production.
