Hi Rob, This patch in AMQ-1521 doesn't seem to fix the issue I was seeing in my previous post.
[producer]-->[broker 1]-->[broker 2]<-->[broker 3]<--[consumer] The messages are successfully dispatched from broker 2 to 3 if there is a producer on broker 2. The messages are not successfully dispatched from broker 1 to 3 however. The messages from 1 get dispatched to broker 2 but never reach broker 3. The networkTTL on all the connections has been set to 5. Configuration of activemq.xml is as follows: Broker1 <networkConnector uri="static:(tcp://broker2:61616)" networkTTL="5"/> Broker2 <!-- No network connectors --> Broker3 <networkConnector uri="static:(tcp://broker2:61616)" duplex="true" networkTTL="5"/> Thanks, Trevor -- View this message in context: http://www.nabble.com/NetworkTTL-and-Duplex-Problem-tp14428941s2354p14694334.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
