Multi-hopping

If there is no direct communication link between the source queue manager and the target queue manager, it is possible to pass through one or more intermediate queue managers on the way to the target queue manager. This is known as a multi-hop.

You need to define channels between all the queue managers, and transmission queues on the intermediate queue managers. This is shown in Figure 11.

Figure 11. Passing through intermediate queue managers
The figure shows three queue managers. In order to send messages to the destination queue on queue manager three (QM3), an intermediate queue manager, QM2, is used. Messages are sent from QM1 to the transmision queue on QM2, and then on to the destination queue on QM3. Channel definitions exist between QM1 and QM2, and between QM2 and QM3.
