Output Fields
Table 1 lists the
output fields for the show (ospf | ospf3) interface command. Output fields
are listed in the approximate order in which they appear.
|
Field Name |
Field Description |
Level of Output |
|---|---|---|
|
Interface |
Name of the interface running OSPF version 2 or OSPF version 3. |
All levels |
|
State |
State of the interface: BDR, Down, DR, DRother, Loop, PtToPt, or Waiting. |
All levels |
|

Address of the area's designated router. |
All levels |
|
BDR ID |
Backup designated router for a particular subnet. |
All levels |
|
Nbrs |
Number of neighbors on this interface. |
All levels |
|
Type |
Type of interface: LAN, NBMA, P2MP, P2P, or Virtual. |
|
|
Address |
IP address of the neighbor. |
|
|
Mask |
Netmask of the neighbor. |
|
|
Prefix-length |
(OSPFv3) IPv6 prefix length, in bits. |
|

|
|
Cost |
Interface cost (metric). |
|
|
DR addr |
Address of the designated router. |
|
|
BDR addr |
Address of the backup designated router. |
|
|
Adj count |
Number of adjacent neighbors. |
|
|
Secondary |
Indicates that this interface is configured as a secondary interface for this area. This interface can belong to more than one area, but can be designated as a primary interface for only one area. |
|
|
Flood Reduction |
Indicates that this interface is configured with flooding reduction. All
self-originated LSAs from this interface are initially sent with the
|
|
|
Priority |
Router priority used in designated router (DR) election on this interface. |
|
|
Flood list |
List of link-state advertisements (LSAs) that might be about to flood this interface. |
|
|
Ack list |
Acknowledgment list. List of pending acknowledgments on this interface. |
|
|
Descriptor list |
List of packet descriptors. |
|
|
Hello |
Configured value for the hello timer. |
|
|
Dead |
Configured value for the dead timer. |
|
|
Auth type |
(OSPFv2) Authentication mechanism for sending and receiving OSPF protocol packets:
|
|
|
Topology |
(Multiarea adjacency) Name of topology: default or name. |
|
|
LDP sync state |
(OSPFv2 and LDP synchronization) Current state of LDP synchronization: in sync, in holddown, and not supported. |
|
|
reason |
(OSPFv2 and LDP synchronization) Reason for the current state of LDP synchronization. The LDP session might be up or down, or adjacency might be up or down. |
|
|
config holdtime |
(OSPFv2 and LDP synchronization) Configured value of the hold timer. If the state is not synchronized, and the hold time is not infinity, the
|
|
|
IPSec SA name |
(OSPFv2) Name of the IPSec security association name. |
|
|
Active key ID |
(OSPFv2 and MD5) Number from 0 to 255 that uniquely identifies an MD5 key. |
|
|
Start time |
(OSPFv2 and MD5) Time at which the routing device starts using an MD5 key to authenticate OSPF packets transmitted on the interface on which this key is configured. To authenticate received OSPF protocol packets, the key becomes effective immediately after the configuration is committed. If the start time option is not configured, the key is effective immediately for send and receive and is displayed as Start time 1970 Jan 01 00:00:00 PST. |
|
|
ReXmit |
Configured value for the Retransmit timer. |
|
