# OSPF Virtual Interface Configuration

Th OSPF Virtual Interface Configuration dialog box displays the virtual 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 Virtual 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 Virtual Interface Configuration from the left pane.

The following information appears:

Transit Area ID (ospfVirtIfAreaID)

Virtual Neighbor's Router ID (ospfVirtIfNeighbor)

Transit Delay for link-state Update (ospfVirtIfTransitDelay)

LSA Retransmission Interval (ospfVirtIfRetransInterval)

Hello Packet Transmission Interval (ospfVirtIfHelloInterval)

Dead Interval for Hello packets (ospfVirtIfRtrDeadInterval)

Interface State (ospfVirtIfState)

Authentication Key (ospfVirtIfAuthKey)

Virtual Interface Entry Valid (ospfVirtIfStatus)

OSPF Virtual Neighbor Configuration

### Transit Area ID (ospfVirtIfAreaID)

Transit area that the virtual link traverses. By definition, this is not 0.0.0.0.

### Virtual Neighbor's Router ID (ospfVirtIfNeighbor)

Router ID of the virtual neighbor.

### Transit Delay for link-state Update (ospfVirtIfTransitDelay)

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

### LSA Retransmission Interval (ospfVirtIfRetransInterval)

Number of seconds between link-state advertisement retransmissions for adjacent packets belonging to the interface. This value is also used when retransmitting database description and link-state request packets. This value should be well over the expected round-trip time.

### Hello Packet Transmission Interval (ospfVirtIfHelloInterval)

Length of time, in seconds, between the Hello packets that the router sends on the interface. This value must be the same for the virtual neighbor.

### Dead Interval for Hello packets (ospfVirtIfRtrDeadInterval)

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 the virtual neighbor.

### Interface State (ospfVirtIfState)

State of the OSPF virtual interface. State can be down (1) or pointToPoint (4).

### Authentication Key (ospfVirtIfAuthKey)

The key used for verification. If authentication type is simplePassword, the device left adjusts and zero fills to 8 octets.

When read, ospfVifAuthKey always returns a string of length zero.

### Virtual Interface Entry Valid (ospfVirtIfStatus)

Indicates the validity or invalidity of the entry. Setting it to invalid has the effect of rendering it inoperative. The internal effect (row removal) is implementation dependent.
