Hi,

 

Thanks for your answer. This is indeed a way to avoid this situation.

 

But here I'm trying to understand why we have this behavior (failover or not in case of equality of the score). It looks like it is link to the management IP for the decision...

    Yes, it uses the management IP to break a tie

    Sorry to bump an old thread. I'm curious to know how the management IP is used as a "tie breaker"? is there a SOL that details this?

    your management ip in F5A is higher than the one in F5B.

    Time to resurrect this thread one year on. I have observed this behaviour also (highest management IP used to break a tie) but I am yet to see this mentioned in any documentation.

    Would be great if someone could post a link (it's not in the Manual chapter: Managing Failover, as posted below).
