network of brokers

[Fausey,Jonathan]

I'm running two brokers on different hosts.  Each has the following (out
of the box) entries in the broker section of conf/activemq.xml, but they
don't seem to have discovered eachother:

    <transportConnectors>
       <transportConnector name="openwire" uri="tcp://localhost:61616"
discoveryUri="multicast://default"/>
       <transportConnector name="ssl"     uri="ssl://localhost:61617"/>
       <transportConnector name="stomp"
uri="stomp://localhost:61613"/>
    </transportConnectors>
    
    <networkConnectors>
      <!-- by default just auto discover the other brokers -->
      <networkConnector name="default-nc" uri="multicast://default"/>
    </networkConnectors>

I confirmed that IPV6 is disabled on both hosts.  Am I missing something
in the broker config?  How can one tell when brokers have discovered
eachother?

Thanks.
