Opened: Apr 09, 2020

Severity: 2-Critical


IPsec Security Associations (SAs) are missing on the standby high availability (HA) device.


During an HA failover, IPsec tunnels may be disrupted because the newly active device is not aware of some IPsec SAs.


-- HA mirroring is configured -- IKEv2 tunnels are started



Fix Information

IPsec SAs are now mirrored correctly to the HA standby device. Note that HA failover for IPsec tunnels is supported only when IKEv2 tunnels are in use.
