Detailed OSPF Interface Output
The following table describes the detailed command output fields for an OSPF interface.
Label
Description  
Interface
The IP address of this OSPF interface.
IP Address
The IP address and mask of this OSPF interface.
Interface Name
The interface name.
Area Id
A 32-bit integer uniquely identifying the area to which this interface is connected. Area ID 0.0.0.0 is used for the OSPF backbone.
Priority
The priority of this interface. Used in multi-access networks, this field is used in the designated router election algorithm.
Hello Intrvl
The length of time, in seconds, between the Hello packets that the router sends on the interface. This value must be the same for all routers attached to a common network.
Rtr Dead Intrvl
The number of seconds that a router's Hello packets have not been seen before it's neighbors declare the router down. This should be some multiple of the Hello interval. This value must be the same for all routers attached to a common network.
Retrans Intrvl
The number of seconds between link-state advertisement retransmissions, for adjacencies belonging to this interface. This value is also used when retransmitting database description and link-state request packets.
Poll Intrvl
The larger time interval, in seconds, between the Hello packets sent to an inactive non-broadcast multi-access neighbor.
Metric
The metric to be advertised for this interface.
Advert Subnet
False
When a point-to-point interface is configured as false, then the subnet is not advertised and the endpoints are advertised as host routes.
 
True
When a point-to-point interface is configured to true, then the subnet is advertised.
Transit Delay
The estimated number of seconds it takes to transmit a link state update packet over this interface.
Auth Type
Identifies the authentication procedure to be used for the packet.
 
None
Routing exchanges over the network/subnet are not authenticated.
 
Simple
A 64-bit field is configured on a per-network basis. All packets sent on a particular network must have this configured value in their OSPF header 64-bit authentication field. This essentially serves as a “clear” 64-bit password.
 
MD5
A shared secret key is configured in all routers attached to a common network/subnet. For each OSPF protocol packet, the key is used to generate/verify a “message digest” that is appended to the end of the OSPF packet.
Passive
False
This interfaces operates as a normal OSPF interface with regard to adjacency forming and network/link behavior.
 
True
no OSPF HELLOs will be sent out on this interface and the router advertises this interface as a stub network/link in its router LSAs.
MTU
The desired size of the largest packet which can be sent/received on this OSPF interface, specified in octets. This size DOES include the underlying IP header length, but not the underlying layer headers/trailers.
Admin Status
Disabled
OSPF on this interface is administratively shut down.
 
Enabled
OSPF on this interface is administratively enabled.
Oper State
Down
This is the initial interface state. In this state, the lower-level protocols have indicated that the interface is unusable.
 
Waiting
The router is trying to determine the identity of the (Backup) Designated router for the network.
 
Point To Point
The interface is operational, and connects either to a physical point-to-point network or to a virtual link.
 
Designated Rtr
This router is the Designated Router for this network.
 
Other Desig Rtr
The interface is operational and part of a broadcast or NBMA network on which another router has been selected to be the Designated Router.
 
Backup Desig Rtr
This router is the Backup Designated Router for this network.
DR-Id
The IP Interface address of the router identified as the Designated Router for the network in which this interface is configured. Set to 0.0.0.0 if there is no Designated router
BDR-Id
The IP Interface address of the router identified as the Backup Designated Router for the network in which this interface is configured. Set to 0.0.0.0 if there is no Backup Designated router.
IF Type
Broadcast
LANs, such as Ethernet.
 
NBMA
X.25, Frame Relay and similar technologies.
 
Point-To-Point
Links that are definitively point to point.
Network Type
Stub
OPSF has not established a neighbor relationship with any other OSPF router on this network as such only traffic sourced or destined to this network will be routed to this network.
 
Transit
OPSF has established at least one neighbor relationship with any other OSPF router on this network as such traffic en route to other networks may be routed via this network.
Oper MTU
The operational size of the largest packet which can be sent/received on this OSPF interface, specified in octets. This size DOES include the underlying IP header length, but not the underlying layer headers/trailers.
Last Enabled
The time that this interface was last enabled to run OSPF on this interface.
Nbr Count
The number of OSPF neighbors on the network for this interface.
If Events
The number of times this OSPF interface has changed its state, or an error has occurred since this interface was last enabled.
Tot Rx Packets
The total number of OSPF packets received on this interface since this interface was last enabled.
Tot Tx Packets
The total number of OSPF packets transmitted on this interface since this interface was last enabled.
Rx Hellos

Tx Hellos
The total number of OSPF Hello packets transmitted on this interface since this interface was last enabled.
Rx DBDs
The total number of OSPF database description packets received on this interface since this interface was last enabled.
Tx DBDs
The total number of OSPF database description packets transmitted on this interface since this interface was last enabled.
Rx LSRs
The total number of Link State Requests (LSRs) received on this interface since this interface was last enabled.
Tx LSRs
The total number of Link State Requests (LSRs) transmitted on this interface since this interface was last enabled.
Rx LSUs

Rx LS Acks
The total number of Link State Acknowledgements received on this interface since this interface was last enabled.
Tx LS Acks
The total number of Link State Acknowledgements transmitted on this interface since this interface was last enabled.
Retransmits
The total number of OSPF Retransmits sent on this interface since this interface was last enabled.
Discards
The total number of OSPF packets discarded on this interface since this interface was last enabled.
Bad Networks
The total number of OSPF packets received with invalid network or mask since this interface was last enabled.
Bad Virt Links
The total number of OSPF packets received on this interface that are destined to a virtual link that does not exist since this interface was last enabled.

Bad Dead Int.
The total number of OSPF packets received where the dead interval given in the packet was not equal to that configured on this interface since this interface was last enabled.
Bad Options
The total number of OSPF packets received with an option that does not match those configured for this interface or area since this interface was last enabled.
Bad Versions
The total number of OSPF packets received with bad OSPF version numbers since this interface was last enabled.
Te Metric
Indicates the TE metric configured for this interface. This metric is flooded out in the TE metric sub-tlv in the OSPF TE LSAs. Depending on the configuration, either the TE metric value or the native OSPF metric value is used in CSPF computations.
Te State

Context
 
show>router>ospf
show>router>ospf3
Description
 
This command will display all neighbor information. To reduce the amount of output the user may opt to select the neighbors on a given interface by address or name.
The detail option produces a large amount of data. It is recommended to use detail only when requesting a specific neighbor.
Parameters
 
ip-int-name
Display neighbor information only for neighbors of the interface identified by the interface name
router-id
Display neighbor information for the neighbor identified by the the specified router ID.
Output
 
Standard OSPF Neighbor Output
The following table describes the standard command output fields for an OSPF neighbor.
Label
Description  
Nbr IP Addr
The IP address this neighbor is using in its IP Source Address. Note that, on addressless links, this will not be 0.0.0.0, but the address of another of the neighbor's interfaces.
Nbr Rtr Id
A 32-bit integer uniquely identifying the neighboring router in the Autonomous System.
Nbr State
Down
This is the initial state of a neighbor conversation. It indicates that there has been no recent information received from the neighbor.
 
Attempt
This state is only valid for neighbors attached to NBMA networks. It indicates that no recent information has been received from the neighbor, but that a more concerted effort should be made to contact the neighbor.
 
Init
In this state, an Hello packet has recently been seen from the neighbor. However, bidirectional communication has not yet been established with the neighbor (i.e., the router itself did not appear in the neighbor's Hello packet).
 
Two Way
In this state, communication between the two routers is bidirectional.
 
ExchStart
This is the first step in creating an adjacency between the two neighboring routers. The goal of this step is to decide which router is the master, and to decide upon the initial Database Descriptor sequence number.
 
Exchange
In this state the router is describing its entire link state database by sending Database Description packets to the neighbor.
 
Loading
In this state, Link State Request packets are sent to the neighbor asking for the more recent LSAs that have been discovered (but not yet received) in the Exchange state.
 
Full
In this state, the neighboring routers are fully adjacent. These adjacencies will now appear in router-LSAs and network-LSAs.
Priority
The priority of this neighbor in the designated router election algorithm. The value 0 signifies that the neighbor is not eligible to become the designated router on this particular network.
RetxQ Len
The current length of the retransmission queue.
Dead Time
The time until this neighbor is declared down, this timer is set to the dead router interval when a valid hello packet is received from the neighbor.
No. of Neighbors
The number of adjacent OSPF neighbors on this interface.

Detailed OSPF Neighbor Output
The following table describes the detailed command output fields for an OSPF neighbor.
Label
Description  
Neighbor IP Addr
The IP address this neighbor is using in its IP source address. Note that, on addressless links, this will not be 0.0.0.0, but the address of another of the neighbor's interfaces.
Local IF IP Addr
The IP address of this OSPF interface.
Area Id
A 32-bit integer uniquely identifying the area to which this interface is connected. Area ID 0.0.0.0 is used for the OSPF backbone

Neighbor Rtr Id
A 32-bit integer uniquely identifying the neighboring router in the AS.
Neighbor State
Down
This is the initial state of a neighbor conversation. It indicates that there has been no recent information received from the neighbor

Backup Desig Rtr
The IP Interface address of the router identified as the Backup Designated Router for the network in which this interface is configured. Set to 0.0.0.0 if there is no backup designated router.
Events
The number of times this neighbor relationship has changed state, or an error has occurred.
Last Event Time
The time when the last event occurred that affected the adjacency to the neighbor.
Up Time
This value represents the uninterrupted time, in hundredths of seconds, the adjacency to this neighbor has been up. To evaluate when the last state change occurred see last event time.
Time Before Dead
The time until this neighbor is declared down, this timer is set to the dead router interval when a valid hello packet is received from the neighbor.
Bad Nbr States
The total number of OSPF packets received when the neighbor state was not expecting to receive this packet type since this interface was last enabled.
LSA Inst fails
The total number of times an LSA could not be installed into the LSDB due to a resource allocation issue since this interface was last enabled.
Bad Seq Nums
The total number of times when a database description packet was received with a sequence number mismatch since this interface was last enabled.
Bad MTUs
The total number of times when the MTU in a received database description packet was larger than the MTU of the receiving interface since this interface was last enabled.
Bad Packets
The total number of times when an LS update was received with an illegal LS type or an option mismatch since this interface was last enabled.
LSA not in LSDB
The total number of times when an LS request was received for an LSA not installed in the LSDB of this router since this interface was last enabled.
Option Mismatches
