        <div>Could you give me some advice for our problem?</div>
        <div><br>
        </div>
        <div>We use Neutron L3-HA.</div>
        <div>When I associate/disassociate floating-ip, the state of ha
          keepalived become MASTER/MASTER state. Then </div>
        <div>Because at that time,the sending of vrrp packet from MASTER
          to BACKUP stop for 40 seconds.</div>
        <div><br>
        </div>
        <div>I checked logs of Keepalived, there is the 40 seconds delay
          of between Log ( Initializing ipvs 2.6) and Log (Opening file
          ~).</div>

        <div>During this time, the packet of vrrp for MASTER to
