Have a look at the following tip:

  http://sources.redhat.com/cluster/faq.html#broadcastmulticast2
  
  How can I configure my RHEL4 cluster to use multicast rather than
  broadcast?

  Put something like this in your cluster.conf file:

  <clusternode name="nd1">
	<multicast addr="224.0.0.1" interface="eth0"/>
  </clusternode>
