Bug ID 929553: Floating IP address might fail to float to the new primary on failover

Last Modified: Jul 12, 2023

Affected Product(s):
BIG-IQ Platform(all modules)

Known Affected Versions:
7.1.0,,,, 7.1.6,, 7.1.7,,, 7.1.8,,,,,, 7.1.9,,,

Opened: Jul 22, 2020

Severity: 3-Major


After a failover event, the floating IP address may still be assigned to the original primary device. In this case, the command "ip address" will show that the floating address is assigned as the primary address on the interface, while the fixed address is assigned as a secondary or temporary address. This is incorrect, as the floating address should always be a secondary or temporary address.


The floating IP will not transfer to the new primary device on failover, but will stay with the original device.


The exact conditions causing this are unknown. It can only occur when the floating address is the first address assigned to the interface, so it may be due to a race condition on boot or when starting network services. It's possible that rebooting or restarting the "network" service might resolve the issue.
