Affected Product:  See more info
BIG-IP LTM(all modules)

Known Affected Versions:
11.6.0, 11.6.0 HF1, 11.6.0 HF2, 11.6.0 HF3, 11.6.0 HF4, 11.6.0 HF5, 11.6.0 HF6, 11.6.0 HF7, 11.6.0 HF8, 11.6.1

Fixed In:
12.0.0, 11.6.1 HF1

Opened: Jul 29, 2014
Severity: 2-Critical


BIG-IP AES-GCM negotiation through IKEv2 does not accept the case of no integrity algorithm. This can happen with the tunnel configured to use AES-GCM.


The IPsec tunnel will not be established.


When configuring IPsec tunnel to use AES-GCM to inter-operate between two BIG-IPs of version 11.6 and 12.0, or configuring IPsec tunnel on a BIG-IP of 11.6 to inter-operate with another vendor using AES-GCM.


For BIG-IP only, ensure both sides of the tunnel are the same release level.

Fix Information

Do not include integrity algorithm for AES-GCM.
