The OSPF Interface Table describes the interfaces from the viewpoint of OSPF.
It augments the ipAddrTable with OSPF specific information.
The indexes of the table are ospfIfIpAddress, ospfAddressLessIf.

1.3.6.1.2.1.14.7.1.1 |
ospfIfIpAddress |
IpAddress |
read-only |
The IP address of this OSPF interface. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.7.1.2 |
ospfAddressLessIf |
Integer32{(0,2147483647)} |
read-only |
For the purpose of easing the instancing of addressed and addressless interfaces; this variable takes the value 0 on interfaces with IP addresses and the corresponding value of ifIndex for interfaces having no IP address. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.7.1.3 |
ospfIfAreaId |
IpAddress |
read-create |
A 32-bit integer uniquely identifying the area to which the interface connects. Area ID 0.0.0.0 is used for the OSPF backbone. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.7.1.4 |
ospfIfType |
INTEGER{broadcast(1),nbma(2),pointToPoint(3),pointToMultipoint(5)} |
read-create |
The OSPF interface type. By way of a default, this field may be intuited from the corresponding value of ifType. Broadcast LANs, such as Ethernet and IEEE 802.5, take the value 'broadcast', X.25 and similar technologies take the value 'nbma', and links that are definitively point to point take the value 'pointToPoint'. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.7.1.5 |
ospfIfAdminStat |
INTEGER{enabled(1),disabled(2)} |
read-create |
The OSPF interface's administrative status. The value formed on the interface, and the interface will be advertised as an internal route to some area. The value 'disabled' denotes that the interface is external to OSPF. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.7.1.6 |
ospfIfRtrPriority |
Integer32{(0,'ff'h)} |
read-create |
The priority of this interface. Used in multi-access networks, this field is used in the designated router election algorithm. The value 0 signifies that the router is not eligible to become the designated router on this particular network. In the event of a tie in this value, routers will use their Router ID as a tie breaker. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.7.1.7 |
ospfIfTransitDelay |

read-create |
The estimated number of seconds it takes to transmit a link state update packet over this interface. Note that the minimal value SHOULD be 1 second. |
The actually supported access is read-only. The value ranges from 1 to 500. |
|
1.3.6.1.2.1.14.7.1.8 |
ospfIfRetransInterval |
Integer32{(0,3600)} |
read-create |
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. Note that minimal value SHOULD be 1 second. |
The actually supported access is read-only. The value ranges from 1 to 3600. |
|
1.3.6.1.2.1.14.7.1.9 |
ospfIfHelloInterval |

read-create |
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. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.7.1.10 |
ospfIfRtrDeadInterval |
Integer32{(0,'7fffffff'h)} |
read-create |
The number of seconds that a router's Hello packets have not been seen before its 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. |
The actually supported access is read-only. The value ranges from 1 to 235926000. |
|
1.3.6.1.2.1.14.7.1.11 |
ospfIfPollInterval |
Integer32{(0,'7fffffff'h)} |
read-create |
The larger time interval, in seconds, between the Hello packets sent to an inactive non-broadcast multi-access neighbor. |
The actually supported access is read-only. The value ranges from 1 to 3600. |
|
1.3.6.1.2.1.14.7.1.12 |
ospfIfState |
INTEGER{down(1),loopback(2),waiting(3),pointToPoint(4),designatedRouter(5),backupDesignatedRouter(6),otherDesignatedRouter(7)} |
read-only |
The OSPF Interface State. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.7.1.13 |
ospfIfDesignatedRouter |
IpAddress |
read-only |
The IP address of the designated router. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.7.1.14 |
ospfIfBackupDesignatedRouter |
IpAddress |
read-only |
The IP address of the backup designated router. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.7.1.15 |
ospfIfEvents |
Counter32 |
read-only |
The number of times this OSPF interface has changed its state or an error has occurred. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ospfDiscontinuityTime. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.7.1.16 |
ospfIfAuthKey |
OCTET STRING{(0,256)} |
read-create |
The simple password used as an OSPF authentication key when simplePassword security is enabled. This object does not access any OSPF cryptogaphic authentication key under any circumstance. If the key length is shorter than 8 octets, the agent will left adjust and zero fill to 8 octets. Unauthenticated interfaces need no authentication key, and simple password authentication cannot use a key of more than 8 octets. Note that the use of simplePassword authentication is NOT recommended when there is concern regarding attack upon the OSPF system. SimplePassword authentication is only sufficient to protect against accidental misconfigurations because it re-uses simple password. [RFC1704] When read, ospfIfAuthKey always returns an octet string of length zero. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.7.1.17 |
ospfIfStatus |
INTEGER{active(1),notInService(2),notReady(3),createAndGo(4),createAndWait(5),destroy(6)} |
read-create |
This object permits management of the table by facilitating actions such as row creation, construction, and destruction. The value of this object has no effect on whether other objects in this conceptual row can be modified. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.7.1.18 |
ospfIfMulticastForwarding |
INTEGER{blocked(1),multicast(2),unicast(3)} |
read-create |
The way multicasts should be forwarded on this interface: not forwarded, forwarded as data link multicasts, or forwarded as data link unicasts. Data link multicasting is not meaningful on point-to-point and NBMA interfaces, and setting ospfMulticastForwarding to 0 effectively disables all multicast forwarding. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.7.1.19 |
ospfIfDemand |
INTEGER{true(1),false(2)} |
read-create |
Indicates whether Demand OSPF procedures (hello suppression to FULL neighbors and setting the DoNotAge flag on propagated LSAs) should be performed on this interface. |
The actually supported access is read-only. |
|
