Example
To get OSPF virtual link information for IP address 10.0.8.33, enter show ip ospf
virtual-link 10.0.8.33. A display similar to the following is shown.
Example 120 Output for the show ip ospf virtual-link ip-addr command
HP Switch# show ip ospf virtual-link 10.0.8.33
OSPF Virtual Interface Status for interface 10.0.8.33

In this display, these fields show the same type of information as described for the general OSPF
virtual link display: Transit Area ID, Neighbor Router, Authentication, and Interface State. This
display shows the following additional information:

Viewing OSPF SPF statistics
Displays the log used to record SPF calculations on an OSPF-enabled routing switch. 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
This 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.
