Subject Re: Problem configuring a "network of brokers"?
Date Wed, 04 Feb 2009 13:48:23 GMT
Hi Bjorn,

this is exactly what network of brokers are supposed to do. Note that broker
will forward a message to other broker only if there is a consumer for that
destination on the other broker. You can ensure that messages go only to the
next broker in the network, by setting networkTTL parameter to 1. You can
also exclude some destinations for a certain network connector and ensure
that messages are never forwarded. Take a look at
http://activemq.apache.org/networks-of-brokers.html for more detailed
examples.

Hope this helps
