Known Affected Versions:
16.1.0, 16.1.1, 16.1.2, 16.1.2.1, 16.1.2.2, 16.1.3, 16.1.3.1, 16.1.3.2, 16.1.3.3, 17.0.0, 17.0.0.1, 17.0.0.2

Opened: Oct 17, 2022
Severity: 2-Critical

Symptoms

After the deletion of an IKE SA, the child IPsec SAs will not be deleted.

Impact

The BIG-IP believes it still has valid IPsec SAs to use, while the remote peer does not. In this case, if the BIG-IP is normally the initiator, the tunnel will be unusable until the lifetime expires on the existing IPsec SAs.

Conditions

-- IKEv2 IPsec tunnels -- Tunnels use Route Domains. -- An IPsec SA is deleted.
