Traffic Redirect

This section details the configuration process for Traffic Redirect.
Metric
The metric sets the priority for the Prestige's routes to the Internet. If any two of the default routes have the
same metric, the Prestige uses the following pre-defined priorities:
1. Normal route: designated by the ISP or a static route.
2. Traffic-redirect route.
3. Dial-backup route.
IP Policy Routing overrides the default routing behavior and takes priority over all
of the routes mentioned above.
For example, if the normal route has a metric of "1" and the traffic-redirect route has a metric of "2" and dial-
backup route has a metric of "3", then the normal route acts as the primary default route. If the normal route
fails to connect to the Internet, the Prestige tries the traffic-redirect route next. In the same manner, the
Prestige uses the dial-backup route if the traffic-redirect route also fails.
If you want the dial-backup route to take first priority over the traffic-redirect route or even the normal route,
all you need to do is set the dial-backup route's metric to "1" and the others to "2" (or greater).
9.1 Traffic Redirect
Traffic redirect forwards WAN traffic to a backup gateway when the Prestige cannot connect to the Internet
through its normal gateway.
