
Failover to the Next Rule - When the specified
interface disconnects due to some reason, the
router can use next route rule to perform data
transmission automatically. Click Enable to
enable such function. Or, click Disable to disable
such function.

When interface down - When the specified
interface (selected by out-going rule)
disconnects, the router will use next rule
match with policy route to perform data
transmission.

When target .....- When certain IP or
domain connects successfully or fails to
connect for several seconds, Vigor router
will treat the selected interface as
disconnected and activate Failover
mechanism. For example, you might
configure settings as:
Out-going Rule : User Defined
Out-going interface : wan1
Failover : Enable
when target [8.8.8.8] ping [Fail] for [5]
seconds
Then, it means even if wan1 connects to
network always, once the target cannot be
detected by Vigor router for 5 seconds, Vigor
router will use next matched rule to perform
data transmission.

Failback (Quick Recover) - When the specified
interface re-connects, the traffic via other interface
will be interrupted immediately. The router will
use the specified interface for data transmission
again. Click Enable to enable such function. Or,
click Disable to disable such function.
Click it to save the configuration.
