Opened: Oct 17, 2022
Severity: 2-Critical


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


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.


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