The configuration is ok and mcast communication is ok too, The problem is
that sync table happens when master server receives a heavy requests and
transitions in port 80, so after this the table is synchronized.

Other thing :

There is a problem in a config default on file "lvs.cfg" the parameter
default in "keepalive" is major than "deadline" , but this should be change
for something like this, example (keepalive  = 12 /  deadline = 4 ) if you
don't change this option all the time if you check on both server "watch
-n.1 "ifconfig" " you will see the virtual interface appearing/disapering in
the backup server.
