This integer defines the time interval during which the
counter update must happen, otherwise the peer is considered to be
inactive. The time interval is given in seconds. The default value is
60
seconds.
PeerAliveDetectionInterval
must be twice as long as
the watchdog trigger time so that at least DWR/DWA are updated. Twinit
default for watchdog trigger time is 30 seconds according to RFC 6733,
thus PeerAliveDetectionInterval
must be minimum 60
seconds. If this parameter is set to 0
, it disables the
peer alive checks.
