Opened: Jul 27, 2023

Severity: 4-Minor

Symptoms

A standby BIG-IP tenant running on an r2000 or r4000 appliance cannot access addresses in the floating traffic group if MAC masquerade is enabled. For instance, the standby tenant will not be able to ping the floating self IP address. External devices can access the floating self IP address without issue. If the tenants swap HA roles (the active device becomes standby, and the standby device becomes active), the problem follows the standby device -- the newly-standby system is not able to ping the floating self IP address.

Impact

Standby tenant unable to access resources in the floating traffic group when MAC masquerade is configured.

Conditions

-- F5 r2000 or BIG-IP r4000 system -- BIG-IP tenant with MAC masquerade configured for floating traffic group
