The Interface tab shows information about the OSPF interface configured on the router.
To open the Interface tab:
| The OSPF dialog box opens with the General tab displayed. |
| The read-only Interface tab opens. |
The table below describes the OSPF, Interface tab items.
IpAddress
The Internet Protocol address of the device used to represent a point of attachment in a TCP/IP internetwork.
AddressLessIf
Used 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.
AreaId
A 32-bit integer uniquely identifying an area. Area ID 0.0.0.0 is used for the OSPF backbone.
Type
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.
AdminStat
The administrative status of OSPF in the router. The value "enabled" denotes that the OSPF process is active on the interface; "disabled" disables it on all interfaces.
RtrPriority
The priority of this interface. Used in multiaccess 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.
TransitDelay
The estimated number of seconds it takes to transmit a link state update packet over this interface.
RetransInterval
The number of seconds between link state advertisement retransmissions. This value is also used for retransmission of database descriptions and link state request packets.
HelloInterval
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.
RtrDeadInterval
The number of seconds that a router's hello packets have not been seen before its neighbors declare the router down. This value should be a multiple of the hello interval and the same for the virtual neighbor.
PollInterval
The larger time interval, in seconds, between the Hello packets sent to an inactive nonbroadcast multiaccess neighbor.
State
The OSPF interface state.
DesignatedRouter
The IP address of the designated router.
Backup
The IP address of the backup designated router.
