Description: The X.25 Routing Table specifies the target link for different call parameters. For each incoming call the route table will be searched for a matching entry. If multiple entries match the call parameters, a metric defines which of them to use. A route is only used, if the state of the target interface is up or dormant (see mib2). Also the state of the link is used to determine wether to use the route or not. With this mechanism, a rerouting scheme can be implemented.
