Description
Display the status of OSPF interfaces.
Options
none | — | Display standard information about the status of all OSPF interfaces for all routing instances |
brief | detail | extensive | — | (Optional) Display the specified level of output. |
area area-id | — | (Optional) Display information about the interfaces that belong to the specified area. |
interface-name | — | (Optional) Display information for the specified interface. |
instance instance-name | — | (Optional) Display all OSPF interfaces under the named routing instance. |
logical-system (all | logical-system-name) | — | (Optional) Perform this operation on all logical systems or on a particular logical system. |
realm (ipv4-multicast | ipv4-unicast | ipv6-multicast) | — | (OSPFv3 only) (Optional) Display information about the interfaces for the specified OSPFv3 realm, or address family. Use the realm option to specify an address family for OSPFv3 other than IPv6 unicast, which is the default. |

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.
Table 1: show (ospf | ospf3) interface Output Fields
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 |
Area | Number of the area that the interface is in. | All levels |
DR ID | 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. | detail extensive |
Address | IP address of the neighbor. | detail extensive |
Mask | Netmask of the neighbor. | detail extensive |
Prefix-length | (OSPFv3) IPv6 prefix length, in bits. | detail extensive |
OSPF3-Intf-Index | (OSPFv3) OSPF version 3 interface index. | detail extensive |
MTU | Interface maximum transmission unit (MTU). | detail extensive |
Cost | Interface cost (metric). | detail extensive |
DR addr | Address of the designated router. | detail extensive |
BDR addr | Address of the backup designated router. | detail extensive |
Adj count | Number of adjacent neighbors. | detail extensive |
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. | detail extensive |
Flood Reduction | Indicates that this interface is configured with flooding reduction. All self-originated LSAs from this interface are initially sent with the DoNotAge bit set. As a result, LSAs are refreshed only when a change occurs. | extensive |
Priority | Router priority used in designated router (DR) election on this interface. | detail extensive |
Flood list | List of link-state advertisements (LSAs) that might be about to flood this interface. | extensive |
Ack list | Acknowledgment list. List of pending acknowledgments on this interface. | extensive |
Descriptor list | List of packet descriptors. | extensive |
Hello | Configured value for the hello timer. | detail extensive |
Dead | Configured value for the dead timer. | detail extensive |
Auth type | (OSPFv2) Authentication mechanism for sending and receiving OSPF protocol packets:
| detail extensive |
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. | extensive |
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. | extensive |
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 remaining field displays the number of seconds that remain until the configured hold timer expires. | extensive |
IPSec SA name | (OSPFv2) Name of the IPSec security association name. | detail extensive |
Active key ID | (OSPFv2 and MD5) Number from 0 to 255 that uniquely identifies an MD5 key. | detail extensive |
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. | detail extensive |
ReXmit | Configured value for the Retransmit timer. | detail extensive |
Stub, Not Stub, or Stub NSSA | Type of area. | detail extensive |
