IfIpAddress |
The IP address of this OSPF interface. |
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. |
IfAreaId |
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. |
IfType |
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 'nbma', and links that are
definitively point to point take the value
'pointToPoint'. Enumerations: - broadcast (1)
- nbma (2)
- pointToPoint (3)
- pointToMultipoint (5)
|
IfAdminStat |
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. This variable is implicitly set by the value of
ipExtIfOspf. Enumerations: |
IfRtrPriority |
The priority of this interface. Used in multi-access
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. |
IfTransitDelay |
The estimated number of seconds it takes to transmit a
link- state update packet over this interface. |
IfRetransInterval |
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. |
IfHelloInterval |
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. |
IfRtrDeadInterval |
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. |
IfPollInterval |
The larger time interval, in seconds, between the
Hello packets sent to an inactive non-broadcast multi-
access neighbor. |
IfState |
The OSPF Interface State. Enumerations: - down (1)
- loopback (2)
- waiting (3)
- pointToPoint (4)
- designatedRouter (5)
- backupDesignatedRouter (6)
- otherDesignatedRouter (7)
|
IfDesignatedRouter |
The IP Address of the Designated Router. |
IfBackupDesignatedRouter |
The IP Address of the Backup Designated Router. |
IfEvents |
The number of times this OSPF interface has changed
its state, or an error has occurred. |
IfAuthKey |
The Authentication Key. If the Area's Authorization
Type is simplePassword, and the key length is shorter
than 8 octets, the agent will left adjust and zero fill
to 8 octets.
When read, ospfIfAuthKey always returns an Octet String
of length zero. |
IfStatus |
This variable displays the status of the en-
try. Setting it to 'invalid' has the effect of
rendering it inoperative. The internal effect
(row removal) is implementation dependent. Enumerations: |
IfMulticastForwarding |
The way multicasts should forwarded on this
interface; not forwarded, forwarded as data
link multicasts, or forwarded as data link uni-
casts. Data link multicasting is not meaning-
ful on point to point and NBMA interfaces, and
setting ospfMulticastForwarding to 0 effective-
ly disables all multicast forwarding. Enumerations: - blocked (1)
- multicast (2)
- unicast (3)
|
IfDemand |
Indicates whether Demand OSPF procedures (hel-
lo supression to FULL neighbors and setting the
DoNotAge flag on propagated LSAs) should be per-
formed on this interface. Enumerations: |
IfAuthType |
The authentication type specified for an in-
terface. Additional authentication types may
be assigned locally. |
