thanks for the quick reply: the mcast address is the same and it
looks like it is using the same VLAN here are the details....

this is one cluster (cluster one):

        <cman expected_votes="1" two_node="1">
                <multicast addr=""/>

and this is in the 2nd cluster (cluster two)......

        <cman expected_votes="1" two_node="1">
                <multicast addr="" interface="eth1"/>

unfortunately eth1 is on the same VLAN for both clusters...is cluster
1 using the mcast address on both adapters?
