I configured two lvs keepalived servers. The first is master server, ip 10.1.88.76, iptables closed. The second is backup server, ip 10.1.88.77, iptables closed. the network connection between two servers is ok (verified by ping)

But, the problem is both servers are in MASTER state. What I expect is one in Master and the other in BACKUP mode.

What should I do to settle the problem? Thank you

I found the solution of this problem. The master virtual_router_id should equal to backup's. –  user1111073 Jun 26 '13 at 6:39

You need to allow vrrp traffic between the two hosts so they can run the heartbeat.

Thank you for your answer. In summery, 1st the virtual_route_id in both master and slave should be same. 2nd we need to allow vrrp traffic between two hosts archive.linuxvirtualserver.org/html/lvs-users/2006-10/…. –  user1111073 Jun 28 '13 at 6:39
