8.6 TCP/IP Priority (Metric)
The metric represents the "cost of transmission". A router determines the best route for
transmission by choosing a path with the lowest "cost". RIP routing uses hop count as the
measurement of cost, with a minimum of "1" for directly connected networks. The number
must be between "1" and "15"; a number greater than "15" means the link is down. The
smaller the number, the lower the "cost".
1
The metric sets the priority for the ZyWALL's routes to the Internet. Each route must
have a unique metric.
2
The priorities of the WAN interface routes must always be higher than the dial-backup
and traffic redirect route priorities.
Lets say that you have the WAN operation mode set to active/passive, meaning the ZyWALL
use the second highest priority WAN interface as a back up. The WAN 1 route has a metric of
"2", the WAN 2 route has a metric of "3", the traffic-redirect route has a metric of "14" and the
dial-backup route has a metric of "15". In this case, the WAN 1 route acts as the primary
default route. If the WAN 1 route fails to connect to the Internet, the ZyWALL tries the WAN
2 route next. If the WAN 2 route fails, the ZyWALL tries the traffic-redirect route. In the same
manner, the ZyWALL uses the dial-backup route if the traffic-redirect route also fails.
The dial-backup or traffic redirect routes cannot take priority over the WAN 1 and WAN 2
routes.
