In Neutron L3 VRRP, when the current master node is rebooted, once it is back up it becomes master again even though all nodes run with same priority and with nopreempt in keepalived.conf. This causes second failover.
Keepalived version is 1.2.13. Any idea what was going wrong? /var/log/messages has information only about spwaning keepalived and nothing about state changes even though -D and -d options are enabled.
