Show Ip Ospf Statistics - NETGEAR M6100 Series Reference Manual

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 command shows statistics for how long ago the SPF ran, how long the SPF took,
the reasons why the SPF was scheduled, the individual components of the routing table
calculation time and to show the RIB update time. The most recent statistics are displayed at
the end of the table.

Term Definition
Delta T The time since the routing table was computed. The time is in the format hours, minutes, and
seconds (hh:mm:ss).
Intra The time taken to compute intra-area routes, in milliseconds.
Summ The time taken to compute inter-area routes, in milliseconds.
Ext The time taken to compute external routes, in milliseconds.
SPF Total The total time to compute routes, in milliseconds. The total may exceed the sum of the Intra, Summ,
and Ext times.
RIB Update The time from the completion of the routing table calculation until all changes have been made in the
common routing table [the Routing Information Base (RIB)], in milliseconds.
Reason The event or events that triggered the SPF. Reason codes are as follows:
• R. New router LSA
• N. New network LSA
• SN. New network summary LSA
• SA. New ASBR summary LSA
• X. New external LSA
