Fixed In:

Opened: Jul 30, 2014
Severity: 2-Critical

Symptoms

For VXLAN tunnels with flooding type "multipoint" and "none", if a tunnel FDB endpoint is missing in the configuration and that endpoint sends traffic to the BIG-IP, memory leak could occur when the BIG-IP receives the traffic.

Impact

Memory leak could occur.

Conditions

Missing a tunnel FDB endpoint in the configuration.

Workaround

Ensure that a tunnel FDB endpoint is configured if that endpoint is expected to send traffic to the BIG-IP.

Fix Information

No memory leak occurs even if a tunnel FDB endpoint is missing in the configuration and that endpoint sends traffic to the BIG-IP.
