| IfIpAddress |
| The IP address of this OSPF interface. |
| AddressLessIf |
| 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. |
| IfAreaId |
| 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. |
| IfType |
| 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, Frame Relay, and similar technologies take the value 'nbma', and links that are definitively point to point take the value 'pointToPoint'. Enumerations: - broadcast (1)
- nbma (2)
- pointToPoint (3)
- pointToMultipoint (5)
|
| IfAdminStat |
| The OSPF interface's administrative status. The value 'enabled' denotes that neighbor relationships may be 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. This variable is implicitly set by the value of ipExtIfOspf. Enumerations: |
| IfRtrPriority |
| 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. Range: 0 to 255 |
| IfTransitDelay |
| The estimated number of seconds it takes to transmit a link- state update packet over this interface. Range: 1 to 3600 |
| IfRetransInterval |
| 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. Range: 1 to 3600 |
| IfHelloInterval |
| 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. Range: 1 to 65535 |
| IfRtrDeadInterval |
| 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. |
| IfPollInterval |
| The larger time interval, in seconds, between the Hello packets sent to an inactive non-broadcast multi- access neighbor. |
| IfState |
| The OSPF Interface State. Enumerations: - down (1)
- loopback (2)
- waiting (3)
- pointToPoint (4)
- designatedRouter (5)
- backupDesignatedRouter (6)
- otherDesignatedRouter (7)
|
| IfDesignatedRouter |
| The IP Address of the Designated Router. |
| IfBackupDesignatedRouter |
| The IP Address of the Backup Designated Router. |
| IfEvents |
| The number of times this OSPF interface has changed its state, or an error has occurred. |
| IfAuthKey |
| The Authentication Key. If the Area's Authorization Type is simplePassword, and the key length is shorter than 8 octets, the agent will left adjust and zero fill to 8 octets. When read, ospfIfAuthKey always returns an Octet String of length zero. Length: 0 to 255 |
| IfStatus |
| This variable displays the status of the en- try. Setting it to 'invalid' has the effect of rendering it inoperative. The internal effect (row removal) is implementation dependent. Enumerations: |
| IfMulticastForwarding |
| The way multicasts should forwarded on this interface; not forwarded, forwarded as data link multicasts, or forwarded as data link uni- casts. Data link multicasting is not meaning- ful on point to point and NBMA interfaces, and setting ospfMulticastForwarding to 0 effective- ly disables all multicast forwarding. Enumerations: - blocked (1)
- multicast (2)
- unicast (3)
|
| IfDemand |
| Indicates whether Demand OSPF procedures (hel- lo supression to FULL neighbors and setting the DoNotAge flag on propagated LSAs) should be per- formed on this interface. Enumerations: |
| IfAuthType |
| The authentication type specified for an in- terface. Additional authentication types may be assigned locally. Range: 0 to 255 |
