The DISPLAY TCPIP,<tcpipjobname>,OMPROUTE,OSPF,NEIGHBOR,
IPADDR=<ip-addr> command displays the statistics and parameters related
to a specific OSPF neighbor. An IP address must be given and detailed
statistics for that neighbor are displayed.
To view a summary of all neighbors, enter the
DISPLAY TCPIP,<tcpipjobname>,OMPROUTE,OSPF,NEIGHBOR command.
Following is a sample output with explanations of entries for a detailed display:

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: |
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. |
