Vinod, Try setting the network connector attribute called 'dynamicOnly' to true as follows.
<networkConnector name="default-nc" dynamicOnly="true" uri="multicast://default"/> This will instruct the broker to forward messages only if there are active consumers at the connected broker. By default, dynamicOnly is set to false.
