Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP TMOS(all modules)

Known Affected Versions:
15.0.1,,,,, 15.1.0,,,,,, 15.1.1, 15.1.2,, 15.1.3,, 16.0.0,, 16.0.1,,

Fixed In:
16.1.0, 15.1.4

Opened: Jun 25, 2020

Severity: 4-Minor


After failover, the active BIG-IP system fails to respond to DPD requests from some of its eNB neighbors, which results in deletion of IKE tunnel peer as well as the BIG-IP system.


Since BIG-IP systems do not respond to DPD requests, eNB deletes the IKE tunnel after a few retries.


-- The BIG-IP is configured with more than 300 IKE/IPsec tunnels. -- The BIG-IP system fails over.
