Monitoring OSPF Routing Information
Purpose
View OSPF routing information, including a summary of OSPF neighbors, interfaces, and statistics.
Action
Select Monitor>Routing>OSPF Information in the J-Web user interface, or enter the following CLI commands:

- show ospf interfaces
- show ospf statistics
Table 242 summarizes key output fields in the OSPF routing display in the J-Web user interface.
Table 242: Summary of Key OSPF Routing Output Fields
Field | Values | Additional Information |
|---|---|---|
| OSPF Interfaces | ||
Details | Tab used to view the details of the selected OSPF. | – |
Interface | Name of the interface running OSPF. | – |
State | State of the interface: BDR, Down, DR, DRother, Loop, PtToPt, or Waiting. | The Down state, indicating that the interface is not functioning, and PtToPt state, indicating that a point-to-point connection has been established, are the most common states. |
Area | Number of the area that the interface is in. | – |
DR ID | ID of the area's designated device. | – |
BDR ID | ID of the area's backup designated device. | – |
Neighbors | Number of neighbors on this interface. | – |
| OSPF Statistics | ||
| Packets tab | ||
Sent | Displays the total number of packets sent. | – |
Received | Displays the total number of packets received. | – |
| Details tab | ||
Flood Queue Depth | Number of entries in the extended queue. | – |
Total Retransmits | Number of retransmission entries enqueued. | – |
Total Database Summaries | Total number of database description packets. | – |
| OSPF Neighbors | ||
Address | Address of the neighbor. | – |
Interface | Interface through which the neighbor is reachable. | – |
State | State of the neighbor: Attempt, Down, Exchange, ExStart, Full, Init, Loading, or 2way. | Generally, only the Down state, indicating a failed OSPF adjacency, and the Full state, indicating a functional adjacency, are maintained for more than a few seconds. The other states are transitional states that a neighbor is in only briefly while an OSPF adjacency is being established. |
ID | ID of the neighbor. | – |
Priority | Priority of the neighbor to become the designated router. | – |
Activity Time | The activity time. | – |
Area | Area that the neighbor is in. | – |
Options | Option bits received in the hello packets from the neighbor. | – |
DR Address | Address of the designated router. | – |
BDR Address | Address of the backup designated router. | – |
Uptime | Length of time since the neighbor came up. | – |
Adjacency | Length of time since the adjacency with the neighbor was established. | – |
