I got a little further today: The reason that conduit does not happen is that even though ConsumerInfos come twice for the same topic, they come over different transport connections and thus come to different bridges. For conduit to happen it must happen within one bridge. Also, I noticed that when A,C and D (spokes) connect to B (hub) they do so over duplex connections. I noticed some special processing for duplex connections, namely that it creates additional bridges, in org.apache.activemq.broker.TransportConnection#processBrokerInfo.
