Score bonus & failover condition
Hello guys,
A question regarding the behavior of the failover in the 11.4.1
Two devices, in active/standby, with a trunk
Active unit bonus score : +10
Bonus per available trunk interface : +10
Initial setup (F5A active):
F5A : 20 (2 int) + 10 (active) = 30
F5B : 20 (2 int) + 0 = 20
With 1 interface shut on F5A :
F5A : 10 (1 int) + 10 (active) = 20
F5B : 20 (2 int) + 0 = 20
=> F5A still active, ok.
With 2 interfaces shut on F5A :
F5A : 0 (0 int) + 10 (active) = 10
F5B : 20 (2 int) + 0 = 20
=> failover on F5B.
With 2 interfaces OK on F5A :
F5A : 20 (2 int) + 0 = 20
F5B : 20 (2 int) + 10 (active) = 30
=> F5B still active, ok.
Until now, everything is logic.
With 1 interface shut on F5B
F5A : 20 (2 int) + 0 = 20
F5B : 10 (1 int) + 10 (active) = 20
=> Failover on F5A !
I don't understand why we have a failover event in this last case. Any explanation ?
