I have configured  the cluster in the lab (  with three nodes) and set the
broadcast. Here is the configuration --

<?xml version="1.0"?>
<cluster alias="test" config_version="61" name="test">
        <fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/>
        <clusternodes>
                <clusternode name="node1" nodeid="1" votes="1">
                        <fence>
                                <method name="1">
                                        <device name="ilo-node1"/>
                                </method>
                        </fence>
                </clusternode>
                <clusternode name="node2" nodeid="2" votes="1">
                        <fence>
                                <method name="1">
                                        <device name="ilo-node2"/>
                                </method>
                        </fence>
                </clusternode>
                <clusternode name="node3" nodeid="3" votes="1">
                        <fence>
                                <method name="1">
                                        <device name="ilo-node3"/>
                                </method>
                        </fence>
                </clusternode>
        </clusternodes>
#---------------------------------------
        <cman>
          <totem broadcast="yes" ip="192.168.205.255"/>
        </cman>
#---------------------------------------

        <fencedevices>
                <fencedevice agent="fence_ilo" hostname="node1r" login="Admin" name="ilo-node1r" passwd="xxx"/>
                <fencedevice agent="fence_ilo" hostname="node2r" login="Admin" name="ilo-node2r" passwd="xxx"/>
                <fencedevice agent="fence_ilo" hostname="node3r" login="Admin" name="ilo-node3r" passwd="xxx"/>
        </fencedevices>
        <rm>
                <failoverdomains/>
                <resources/>
        </rm>
        <dlm plock_ownership="1" plock_rate_limit="0"/>
        <gfs_controld plock_rate_limit="0"/>
</cluster>


When I am executeing  the cman_tool status command  , getting the following output

[root  ~]# cman_tool status
Version: 6.2.0
Config Version: 61
Cluster Name:  test
Cluster Id: 25790
Cluster Member: Yes
Cluster Generation: 968
Membership state: Cluster-Member
Nodes: 3
Expected votes: 3
Total votes: 3
Quorum: 2  
Active subsystems: 7
Flags: Dirty 
Ports Bound: 0  
Node name: node1
Node ID: 1
Multicast addresses: 239.192.xxx.xx 
Node addresses: 192.168.205.1 

Would  you pl. confirm the broadcast  configuration!! 

Again ,in the following document

https://access.redhat.com/kb/docs/DOC-40821

 under Unsopported items/ Netowrking, it is telling that broadcast is not supportive...

Thanks and regards.
