Support fast failover for FortiExtender

This enhancement ensures that FortiGate can swiftly recover data sessions in the event of a failover. You can set a FortiExtender up with two sessions, Active and Standby, which are each associated with a primary and secondary FortiGate.

Upon receiving a failover notification, FortiExtender switches the Standby session associated with the now primary Access Controller (AC) to Active, and the Active session associated with the previous primary AC to Standby.
