show ip ospf statistics

This command displays information about recent Shortest Path First (SPF)
calculations. The SPF is the OSPF routing table calculation. The output lists the
number of times the SPF has run for each OSPF area. A table follows this information.
For each of the 15 most recent SPF runs, the table lists how long ago the SPF ran, how
long the SPF took, and the reasons why the SPF was scheduled.
