Maybe you are right Martijn. I have copied manually cluster.conf from node02 to 
node01 and all works ok (node01 joins to cluster). But If mutlicast is the problem, 
why node01 joins to cluster if cluster.conf it is at same version than on node02??

My problem only occurs when cluster.conf version is different between nodes ...
