3.7.51 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.
Format
show ip ospf statistics
Modes Privileged EXEC
User EXEC
Delta T How long ago the SPF ran. The time is in the format hh:mm:ss, giving
the hours, minutes, and seconds since the SPF run.
SPF Duration How long the SPF took in milliseconds.
Reason
The reason the SPF was scheduled. Reason codes are as follows:
R - a router LSA has changed
N - a network LSA has changed
