Usage Guidelines This command causes OSPF to unregister from the unicast RIB when OSPF shuts down. The unicast RIB
removes all the routes associated with this OSPF instance. If you do not configure the flush-routes
command, OSPF does not unregister and the OSPF routes will be stale. The OSPF routes are eventually
removed from the unicast RIB after a timeout period.
This command requires the LAN Base Services license.
