Force Shortest-Path Calculation Updates
Force the switch to update its shortest-path calculations so that the switch uses the latest OSPF routing information. Manually initiate a shortest path first (SPF) run, or calculation, to immediately update the OSPF LSDB. This action is useful in the following circumstances:
when you need to immediately restore a deleted OSPF-learned route
when the routing table entries and the LSDB do not synchronize
Before you begin
You can perform this procedure in one of the following CLI modes: User EXEC, Privileged EXEC, or Global Configuration.
