– |
|
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. |

– |
|
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. |
