[Pacemaker] Multiple ha clusters on same network

We have about 8 virtual machines on the same network and each pair is in ha mode.
This causes some massive log files which contain only the following log lines:
WARN: string2msg_ll: node [virtualmachinename] failed authentication

The ha.cf file is the same on all machines, except for the node part.

I found a topic which explained this could be the cause of the bcast config, which makes sense.

autojoin none
bcast eth0
bcast eth1
auto_failback on
debugfile /var/log/ha-debug
logfile /var/log/ha-log
warntime 3
deadtime 6
initdead 60
keepalive 1
node virtualmachine01
node virtualmachine02
crm respawn

Could I use the ucast directive instead of the bcast directive like in http://manpages.ubuntu.com/manpages/oneiric/man5/ha.cf.5.html?
