Further to the original question: how does the BIG-IP select the health monitor source IP if there are multiple Self IP's on the same interface / VLAN?
Is there a rules set to define this, and can it be manually set for deterministic monitoring?
Hi Pete, thanks for responding!
I understand the self IP and routing options in terms of interface, but I must be missing something... If I have two IP's on the same interface that is also used for the default route, which one would it choose [out of the box].
I ask because I have just rebooted two BIG-IP appliances that have this configuration, and the health monitors were using say 10.1.1.10, but after reboot switched to using 10.1.1.8. The latter IP was configured after the last reboot to be used for BIGIP DNS but this was the 1st time it has been rebooted since.
Am I missing something fundamental here?
