Interface Configuration

Device > Configure > Open Shortest Path First (OSPF) > Open Shortest Path First (OSPF) > Interface Configuration

This dialog box provides the interface configuration information for OSPF on this device.

To view the definition for a particular MIB variable, click the appropriate link from the following list:

The following list specifies buttons in this dialog box, as well as their function:


Interface IP Address (ospfIfIpAddress)

IP address of this OSPF interface.


Interface without IP Address (ospfAddressLessIf)

This object eases the instancing of interfaces with and without IP addresses. On interfaces with an IP address, the value of this object is zero. On interfaces without an IP address, the value of this object is equal to the corresponding value of ifIndex.


Interface connected Area ID (ospfIfAreaId)

32-bit integer that uniquely identifies the area the interface connects to. The area ID for the OSPF backbone is "0.0.0.0".


Interface Type (ospfIfType)

Indicates the OSPF interface type:


Interface Admin. Status (ospfIfAdminStat)

Administrative status for this OSPF interface:


Priority for DR election (ospfIfRtrPriority)

Indicates the priority of this interface. In multi-access networks, this object is used in the designated router election algorithm. The value "0" indicates that the router is not eligible to become the designated router on this particular network.


Transit Delay for link-state Update (ospfIfTransitDelay)

Estimated number of seconds needed to transmit a link-state update packet over this interface.


LSA Retransmission Interval (ospfIfRetransInterval)

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.


Hello Packet Transmission Interval (ospfIfHelloInterval)

Length of time, in seconds, between Hello packet transmissions. This value must be the same for all routers attached to a common network.


Dead Interval for Hello Packets (ospfIfRtrDeadInterval)

Number of seconds that a router's Hello packets are not recognized before neighbor devices declare the router down. The value of this object should be a multiple of the Hello interval, and must be the same for all routers attached to a common network.


Interval - Poll an inactive NBMA (ospfIfPollInterval)

The length of time, in seconds, between Hello packet transmissions to an inactive non-broadcast multi-access neighbor.


Interface State (ospfIfState)

Indicates the OSPF interface state.


IP Address of Designated Router (ospfIfDesignatedRouter)

IP address of the designated router.


IP Address of Backup DR (ospfIfBackupDesignatedRouter)

IP address of the backup designated router.


Authentication Key (ospfIfAuthKey)

Authentication key for this OSPF interface. If the area's authorization type is set to "simplePassword" and the key length is shorter than 8 octets, the agent appends the number of zeros necessary to create an 8 octet string to the end of the key.

When read, this object always returns a zero-length string.
