routed by this rule.
The IP subnet mask is the subnet mask for the final destination.
A gateway does the actual forwarding of the packets. Enter the gateway’s IP address in
the field or select which PVC you wish to act as a gateway.
The metric is a rough estimate of the “cost” of transmission for routing purposes. IP
routing uses hop count as the measurement of cost, with a minimum of 1 for directly connected
networks. As a rough estimate, enter a number that approximates the cost for this link. The
number must be within 1 and 15, inclusive. Generally, 2 or 3 is a good number to use.
If the route is announced in RIP, the route will be sent to other hosts through RIP
broadcasts. If not announced, the route is private and not included in RIP broadcasts.
