Decision making in a Active Active senario
Hi,
I have an issue I need to find a solution for. In a setup I have one redundant link between the Active/Standby pair. Both management and our HA VLAN goes over this link. The F5:s are in different datacenter. This link is on one ISP but on two different pats.
In the worst case senario and this LACP link goes down the BigIPs both go Active. When the link returns to normal operations I want the BigIP on site1 to be active and the one on site2 to be standby. But I get it the other way around. What I have found is that this probably is caused due to site2 BigIP has a higher IP address on the management interface compared to the one on site1. The management addresses are on different subnets so its not just to change the IP address.
Does anyone has solution for my problem? I don't want to use the Auto Fallback function because I want to do a controlled manual failover if the primary one fail.
Best Regards Andréas
