Severity: 3-Major


In a BIG-IP high availability (HA) configuration with connection mirroring, where the system has failed over to a secondary mirroring address, the system will fail back over to the primary address once it becomes available again.


Mirrored connections on the peer unit are cleared when the failover back to the primary mirroring address occurs.


-- Two BIG-IP devices configured for HA. -- Connection mirroring enabled. -- Have a primary and secondary mirroring address. -- Primary address is down, then comes online.



Fix Information

Mirroring address remains on the secondary system (until a failover causes it to switch back to the primary).
