Passing the messages through multiple qmgr’s to reach Destination QMGR is called MultiHopping .
Example TEST.QM1 -> TEST.QM2 -> TEST.QM3 -> TEST.GM4
In General if we have 2 QMGR’S then to pass message from TEST.QM1 to TEST.QM2 we need Sender ,Receiver channel ,Xmitq,Remote Queue and a Local Queue .
In our case we have 2 QMGR’s in between TEST.QM1 and TEST.QM4. TEST.QM2 & TEST.QM3 will need a queue-manager aliases since they are non-adjacent (don’t have a transmission queue) to the destination QMGR.

Now test by sending message in TEST.QM1 SOURCEQR . message should arrive in DESTQL on TEST.QM4
[mqm@ip-172-31-14-154 bin]$ /opt/mqm/samp/bin/amqsput SOURCEQR TEST.QM1
Sample AMQSPUT0 start
target queue is SOURCEQR
AAAAA
BBBBB
CCCCC
DDDDD
EEEEE
Sample AMQSPUT0 end
[mqm@ip-172-31-14-154 bin]$Verify the message received on TEST.QM4 DESTQL queue .
[mqm@ip-172-31-14-154 bin]$ /opt/mqm/samp/bin/amqsget DESTQL TEST.QM4
Sample AMQSGET0 start
message <AAAAA>
message <BBBBB>
message <CCCCC>
message <DDDDD>
message <EEEEE>
no more messages
Sample AMQSGET0 end
[mqm@ip-172-31-14-154 bin]$ Hope this clarify MQ Hopping Technique with MQGR alias …
