Broker clustering with Mutlicast not working

I have two brokers, both embedded inside JBoss running on two different 
machines within the same network. I  have the following network and 
transport settings for the brokers:

Broker1:
       <networkConnectors>
          <networkConnector uri="multicast://default"/>
        </networkConnectors>

<transportConnector uri="tcp://localhost:0" 
discoveryUri="multicast://default"/>


Broker2:
        <networkConnectors>
          <networkConnector uri="multicast://default"/>
        </networkConnectors>

<transportConnector uri="tcp://localhost:0" 
discoveryUri="multicast://default"/>


When i run the two brokers with these settings i see the network bridge 
error. But running two brokers with the same settings on my local machine 
runs fine.

Related question is that if i have a producer and consumer with the 
following connection property:
 <property name="brokerURL" 
value="discovery:(multicast://default)?initialReconnectDelay=100"/> 

provided the two brokers are connected, does it mean that when i send the 
message to the Queue running on one broker it would be copied to the other 
broker too? And does
it mean that it would be consumed twice?


Thanks!

Can u use the 0.0.0.0 wildcard or ip address in the transport
connector instead of localhost.
A network is store nd forward, not replication, so a message will only
be on one of the brokers.
