The fields for this output are:

NEIGHBOR IP ADDRESS

Displays the neighbor's interface IP address.

OSPF ROUTER ID

Neighbor OSPF router ID.

NEIGHBOR STATE

Can be one of the following:
1 (Down) 2 (Attempt) 4 (Init) 8 (2-Way) 16 (ExStart) 32 (Exchange) 64 (Loading) 128 (Full)
For more information about these values, refer to RFC 1583.

PHYSICAL INTERFACE

Displays the name of the interface over which a relationship has been established with this neighbor.

DR CHOICE, BACKUP CHOICE, DR PRIORITY

Indicate the values seen in the last hello received from the neighbor.

NBR OPTIONS

Indicates the optional OSPF capabilities supported by the neighbor. These capabilities are denoted by E (processes type 5 externals; when this is not set the area to which the common network belongs has been configured as a stub), T (can route based on TOS), MC (can forward IP multicast datagrams), and DC (can support demand circuits). This field is valid only for those neighbors in state Exchange or greater.

DB SUMM QLEN

Indicates the number of advertisements waiting to be summarized in Database Description packets. It should be zero except when the neighbor is in state Exchange.

LS RXMT QLEN

Indicates the number of advertisements that have been flooded to the neighbor, but not yet acknowledged.

LS REQ QLEN

Indicates the number of advertisements that are being requested from the neighbor in state Loading.

LAST HELLO

Indicates the number of seconds since a hello has been received from the neighbor.

NO HELLO

Indicates whether Hello Suppression is active with the neighbor.

# LS RXMITS

Indicates the number of retransmissions that have occurred during flooding.

# DIRECT ACKS

Indicates responses to duplicate link state advertisements.

# DUP LS RCVD

Indicates the number of duplicate retransmissions that have occurred during flooding.

# OLD LS RCVD

Indicates the number of old advertisements received during flooding.

# DUP ACKS RCVD

Indicates the number of duplicate acknowledgments received.

# NBR LOSSES

Indicates the number of times the neighbor has transitioned to Down state.

# ADJ. RESETS

Counts entries to state ExStart.
