Severity: 3-Major

Symptoms

Some of the floating object's IPs might not be reattached to the instance acting as the new active device.

Impact

Potential traffic disruption. Some of the floating object's IPs might not be reattached to the instance acting as the new active device.

Conditions

AWS deployments where there are multiple coincidences for the provided IP address (corresponding to other Amazon VPCs in the same Availability Zone containing unrelated instances but having the same IP address as the BIG-IP's floating IP address.

Workaround

Do not have AWS deployments with multiple VPCs sharing the same IP address as the BIG-IP's floating IP address.

Fix Information

Failover now narrows network description by filtering with VPC id.
