vrIpOspfExportMetric
Virtual Router Ip Ospf Export Metric
This attribute specifies the metric to be used on the routes being exported as a result of matching this export policy. If the attribute advertiseStatus is set to block, then the value of metric is ignored. The metric value is not used to select which routes to block or send, but rather the metric value advertised for the routes. A value of -1 indicates that the metric associated with the route in the forwarding table is used.
