ExternLSACksumSum. The 32-bit unsigned sum of the LS checksums of the external link-state advertisements contained in the link-state database. This sum can be used to determine if there has been a change in a router's link-state database, and to compare the link-state database of two routers.
OriginateNewLSAs. The number of new link-state advertisements that have been originated. This number is incremented each time the router originates a new LSA.

LSACount. The total number of link-state advertisements in this area's link-state database, excluding AS External LSAs.
LSACksumSum The 32-bit unsigned sum of the link-state advertisements LS checksums contained in this area's link-state database. This sum excludes external (LS type 5) link-state advertisements. The sum can be used to determine if there has been a change in a router's link state database, and to compare the link-state database of two routers.
ImportSummary.The area's support for importing Summary advertisements into a stub area. This field should be used only if ospfImportASExtern is set to False.
ActiveIfCount.This variable displays the number of active interfaces configured in this area. An area cannot be deleted if this value is > 0.
TOS. The Type of Service associated with the metric. On creation, this can be derived from the instance.
Metric. The metric value applied at the indicated type of service. By default, this equals the least metric at the type of service among the interfaces to other areas.
Status This variable displays 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.
Type. The type of the link-state advertisement. Each link-state type has a separate advertisement format.
LSID. The Link State ID is an LS Type Specific field containing either a router ID or an IP address; it identifies the piece of the routing domain that is being described by the advertisement.
RouterId. The 32-bit number that uniquely identifies the originating router in the autonomous system.
Sequence. The sequence number field is a signed 32-bit integer. It is used to detect old and duplicate link-state advertisements. The space of sequence numbers is linearly ordered. The larger the sequence number, the more recent the advertisement.
Age. The age of the link-state advertisement in seconds.
Checksum. The checksum of the complete contents of the advertisement, excepting the age field. The age field is excepted so that an advertisement's age can be incremented without updating the checksum. The checksum used is the same that is used for ISO connectionless datagrams; it is commonly referred to as the Fletcher checksum.
Net. The IP Address of the net or subnet indicated by the range.
Mask. The subnet mask that pertains to the net or subnet.
Summary Link Advertisements are generated based on the configured ranges in an area. If there is no match for the given interface in the ranges configured, that interface automatically belongs to the backbone.
TOS. The Type of Service of the route being configured.
Metric. The metric to be advertised to other areas.
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.
TOS. The Type of Service metric being referenced. On row creation, this can be derived from the instance.
Metric. The metric of using this type of service on this interface. The default value of the TOS 0 Metric is 10^8 / ifSpeed.
The value FFFF is distinguished to mean 'no route via this TOS.'
Only TOS 0 is supported at this time
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.
AreaId. 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.
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, Frame Relay, and similar technologies take the value 'nbmap;' links that are definitively point-to-point take the value 'pointToPoint'.
AdminStat. 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.
RtrPriority. The priority of this interface. Used in multi-access networks 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 for adjacencies belonging to this interface. This value is also used when retransmitting database description 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 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.
PollInterval. The larger time interval, in seconds, between Hello packets sent to an inactive non-broadcast multi-access neighbor.
State. The OSPF Interface state.
DesignatedRouter. The IP Address of the designated router.

When read, ospfIfAuthKey always returns an Octet String of length zero.
AddressLessIndex. On an interface having an IP Address, zero. On addressless interfaces, the corresponding value of ifIndex in the Internet Standard MIB. On row creation, this can be derived from the instance.
RtrId. A 32-bit integer (represented as a type IpAddress) uniquely identifying the neighboring router in the Autonomous System.
Options. A bit mask corresponding to the neighbor's options field.
Bit 0, if set, indicates that the area accepts and operates on external information; if zero, it is a stub area.
Bit 1, if set, indicates that the system will operate on Type of Service metrics other than TOS 0. If zero, the neighbor will ignore all metrics except the TOS 0 metric.
Priority. The priority of this neighbor in the designated router election algorithm. The value 0 signifies that the neighbor is not eligible to become the designated router on this particular network.

Events. The number of times this neighbor relationship has changed state or an error has occurred.
LSRetransQLen. The current length of the retransmission queue.

Neighbor. The Router ID of the Virtual Neighbor.
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 for adjacencies belonging to this 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.
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 the virtual neighbor.
