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.

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.
