As described under Enabling route redistribution, you can configure the routing switch to redistribute connected, static, and RIP routes into OSPF. When you redistribute a route into OSPF, the routing switch can use OSPF to advertise the route to its OSPF neighbors.
To display the status of the OSPF redistribution, enter show ip ospf redistribute at any CLI context level:
Example of output for show ip ospf redistribute
HP Switch# show ip ospf redistribute OSPF redistributing Route type Status ---------- -------- connected enabled static enabled rip enabled
The display shows whether redistribution of each of the route types, connected, static, and RIP is enabled.
As described under Configuring external route redistribution in an OSPF domain (optional), you can configure the redistribution filters on the routing switch to restrict route redistribution by OSPF.
To display the status of the OSPF redistribution filters, enter show ip ospf restrict at any CLI context level.
If virtual links are configured on the routing switch, you can display OSPF virtual neighbor information.

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 Transit AreaID : 10.3.16.0 Neighbor Router : 10.0.8.33 Authentication : none Chain : Interface State : P2P Transit Delay : 1 Events : 1 Rtr Interval : 5 Dead Interval : 40 Hello Interval : 10
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:
CLI display of OSPF virtual link information—Specific IP address
| Field | Description |
|---|---|
| Events |
The number of times the virtual link interface state has changed. |
| Transit delay |
The configured transit delay for the virtual link. |
| Rtr Interval |
The configured retransmit interval for the virtual link. |
| Hello Interval |
The configured hello interval for the virtual link. |
| Dead Interval |
The configured router dead interval for the virtual link. |
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:
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.

CLI display of OSPF SPF statistics
area [area id | ip-address] |
ID number or IP address of an area to which the switch is assigned, including the number of times the SPF algorithm was executed to recalculate OSPF routes in the area. |
| SPF instances | Last ten instances in which the SPF algorithm was executed to recalculate an OSPF route in the area. |
| Reason | The event or reason why the SPF algorithm was executed. |
| Time | Time when the SPF computation began. |
Syntax:
To display OSPF route and other OSPF configuration information, enter
show ip ospfat any CLI level.

CLI display of OSPF route and status information
| Field | Description |
|---|---|
|
OSPF protocol |
enabled or disabled — indicates if OSPF is currently enabled. |
|
Router ID |
The router ID that this routing switch is currently using to identify itself. |
| Currently defined areas: | |
|
Area ID |
The identifier for this area. |
|
Type |
The type of OSPF area (normal or stub.) |
|
Stub Default Cost |
The metric for any default route we injected into a stub area if the routing switch is an ABR for the area. This value applies only to stub areas. |
|
Stub Summary LSA |
send or don't send — indicates the state of the no-summary option for the stub area. The value indicates if the area is "totally stubby" (no summaries sent from other areas) or just "stub" (summaries sent.) Applies only to stub areas and takes effect only if the routing switch is the ABR for the area. |
|
Stub Metric Type |
This value is always ospf metric. |
| Currently defined address ranges: | |
|
Area ID |
The area where the address range is configured. |
|
LSA Type |
This value is always Summary. |
|
IP Network |
The address part of the address range specification. |
|
Network Mask |
The mask part of the address range specification. |
|
Advertise |
Whether advertising (yes) or suppressing (no) this address range. |
| Cost | The cost of the interface connection between one switch and another, which is determined by the bandwidth in mega bits per second. The OSPF protocol determines the interface connection cost of each neighbor and uses these costs to determine the best path to reach a destination. The cost can range from a minimum of 1 to a maximum of 10. The faster the connection, the lower the cost. For example, a fast Ethernet interface cost is 1 and a Ethernet interface cost is 10. |

In the default configuration, OSPF traps are disabled. Use this command to view which OSPF traps have been enabled.
Syntax:
Lists the OSPF traps currently enabled on the routing switch.
