Bug ID 1091313: Rapid transition of BIG-IP Next tenant from Standby-to-Active-to-Standby can leave floating addresses active

Last Modified: Dec 07, 2023

Affected Product(s):
F5OS Velos(all modules)

Fixed In:
F5OS-C 1.5.0

Opened: Mar 29, 2022

Severity: 2-Critical

Symptoms

A rapid transition of a BIG-IP Next tenant from Standby-to-Active-to-Standby can leave the floating IP address active even though the tenant is in Standby.

Impact

The high availability (HA) floating address remains active on both instances of the BIG-IP Next tenant, causing high availability (HA) issues with the tenant.

Conditions

This happens only if the transition to Active and back to Standby happens in under 40 seconds or so.

Workaround

If this condition occurs, effect a failover on the BIG-IP Next tenant. This causes the address to be removed on the previously Active instance. If failover is unsuccessful, wait for 60 seconds and issue one more failover.

Fix Information
