Displaying OSPF SPF Statistics
To display the log used to record shortest-path-first (SPF) calculations on an
OSPF-enabled routing switch, enter the
show ip ospf spf-log command at any
CLI level. The SPF algorithm recalculates the routes in an OSPF domain when
a change in the area topology is received.
Syntax: show ip ospf spf-log
The
show ip ospf spf-log command output displays:
■
The number of times that the SPF algorithm was executed for each OSPF
area to which the routing switch is assigned
■
The event that resulted in the last ten executions of the SPF algorithm on
the routing switch. Possible events (reasons) are as follows:
•
Re-Init: OSPF was enabled or disabled on the routing switch.
•
Router LS Update: A router (type 1) link-state advertisement was
received.
•
Network LS Update: A network (type 2) link-state advertisement was
received.
•
Generated RTR LSA: A router (type 1) link-state advertisement was
generated on the routing switch.
•
Generated NTW LSA: A network (type 2) link-state advertisement was
generated on the routing switch.
