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

During this time, the packet of vrrp for MASTER to BACKUP,so BACKUP
changes to MASTER, and then original MASTER starts sendding vrrp
packets again.
The versions of our environment is below
- Keepalived v1.2.7 (08/14,2013)
- Linux stg-anlk-ctrl003 3.13.0-74-generic #118-Ubuntu SMP Thu Dec 17
22:52:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
We did a adjustement of ha_vrrp_advert_int to avoid this.
But I would like to know why is the term always 40 seconds.
If you know anything about that please let me know.
Regards
Ikuo Kumagai
