OSPF Interface Configuration

The OSPF Interface Configuration dialog box displays the interface configuration details of OSPF.

Procedure

For CiscoView versions earlier than 5.2:

  1. Right-click the device. Then select Configure, or double-click the device.

  2. Select Protocols from the Category list.

  3. Select OSPF from the SelectProtocol list. Then click the Details button. The OSPF Configuration dialog box appears.

  4. Select Interface Configuration from the Category list.

For CiscoView version 5.2 and later:

  1. Right-click the device. Then select Configure, or double-click the device.

  2. Select Protocols from the Category list.

  3. Select OSPF from the SelectProtocol list. Then click the Details button. The OSPF Configuration dialog box appears.

    Note: The left frame in the dialog box displays the categories and the right frame displays the category details or a table. If a table is displayed, the variable on which the table is indexed and the key values of the index are listed below the category. Double-click the category to view the table and double-click a key value to view details of a particular row in the table.

    Multiple indexes for a table, if any, are listed below the category in a nested manner. Select a key value to view the rows of the table about that value. Select a key value of the lowest indexing variable to view the details of that particular row.

  4. Select Interface Configuration from the left pane.

The following information appears:

Interface IP Address (ospfIfIpAddress)

Interface without IP Address (ospfAddressLessIf)

Interface connected Area ID (ospfIfAreaId)

Interface Type (ospfIfType)

Interface Admin. Status (ospfIfAdminStat)

Priority for DR election (ospfIfRtrPriority)

Transit Delay for link-state Update (ospfIfTransitDelay)

LSA Retransmission Interval (ospfIfRetransInterval)

Hello Packet Transmission Interval (ospfIfHelloInterval)

Dead Interval for Hello packets (ospfIfRtrDeadInterval)

Interval - Poll an inactive NBMA (ospfIfPollInterval)

Interface State (ospfIfState)

IP Address of Designated Router (ospfIfDesignatedRouter)

IP Address of Backup DR (ospfIfBackupDesignatedRouter)

Authentication Key (ospfIfAuthKey)

Interface IP Address (ospfIfIpAddress)

IP address of this OSPF interface.


Interface without IP Address (ospfAddressLessIf)

Used to ease the occurrances of addressed and addressless interfaces; the object takes the value 0 on interfaces with IP addresses, and the corresponding value of ifIndex for interfaces having no IP address.


Interface connected Area ID (ospfIfAreaId)

32-bit integer that uniquely identifies the area to which the interface connects. Area ID 0.0.0.0 is used for the OSPF backbone.


Interface Type (ospfIfType)

Type of OSPF interface.

By 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 (1), X.25, Frame Relay, and similar technologies take the value nbma (2), and links that are definitively point to point take the value pointToPoint (3).


Interface Admin. Status (ospfIfAdminStat)

Administrative status of the OSPF interface. Administrative status can be:

Value

Description

enabled

Neighbor relationships may be formed on the interface, and the interface is advertised as an internal route to some area

disabled

Interface is external to OSPF


Priority for DR election (ospfIfRtrPriority)

Priority of the interface used in multiaccess networks. It is used in the designated router election algorithm IDs as tie breakers.


Transit Delay for link-state Update (ospfIfTransitDelay)

Estimated number of seconds it takes to transmit a link-state update packet over the interface.


LSA Retransmission Interval (ospfIfRetransInterval)

Interval, in seconds, between link-state advertisement retransmissions for neighbouring packets belonging to the 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 the Hello packets that the router sends on the interface. 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 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.


Interval - Poll an inactive NBMA (ospfIfPollInterval)

Larger time interval, in seconds, between the sending of hello packets to an inactive non-broadcast multi-access neighbor.


Interface State (ospfIfState)

State of the OSPF interface. Interface state can be:

Value

Description

1

down

2

loopback

3

waiting

4

pointToPoint

5

designatedRouter

6

backupDesignatedRouter

7

otherDesignatedRouter


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)

Key used for authorization. If the area authorization type is simplePassword, and the key length is shorter than 8 octets, the agent left-adjusts and zero-fills to 8 octets.

When read, ospfIfAuthKey always returns an octet string of length zero.
