When an Real-time performance monitoring (RPM) probe is successful, IP monitoring adds one or many primary routes to the routing table. Junos OS introduced the option withdraw to remove the primary routes when RPM fails to probe the destination. When the primary routes are withdrawn, the traffic can choose other routes in the routing table. If no other routes exists, then the traffic is dropped. When an RPM probes fails, IP monitoring adds a backup route. If the probe is later successful, the backup route is deleted. To enable the withdraw option, use the set services ip-monitoring policy policy-name then preferred-route withdraw command.
