class OSPFMIB.OspfIfTable.OspfIfEntry

Bases: Entity

Class Hierarchy : OSPFMIB OspfIfTable OspfIfEntry

This class represents state data.

The OSPF interface entry describes one interface

from the viewpoint of OSPF.

Information in this table is persistent and when this object

is written the entity SHOULD save the change to non-volatile

storage.

ospfifipaddress(key)

The IP address of this OSPF interface

type: str

pattern: (([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(%[\p{N}\p{L}]+)?

config: False

ospfaddresslessif(key)

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

type: int

range: 0..2147483647

config: False

ospfifareaid

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: str

pattern: (([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(%[\p{N}\p{L}]+)?

config: False

ospfiftype

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’

type: OspfIfType

config: False

ospfifadminstat

The OSPF interface’s administrative status. The value 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

type: Status

config: False

ospfifrtrpriority

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

type: int

range: 0..255

config: False

ospfiftransitdelay

The estimated number of seconds it takes to transmit a link state update packet over this interface. Note that the minimal value SHOULD be 1 second

type: int

range: 0..3600

config: False

units: seconds

ospfifretransinterval

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. Note that minimal value SHOULD be 1 second

type: int

range: 0..3600

config: False

units: seconds

ospfifhellointerval

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

type: int

range: 1..65535

config: False

units: seconds

ospfifrtrdeadinterval

The number of seconds that a router’s Hello packets have not been seen before its 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

type: int

range: 0..2147483647

config: False

units: seconds

ospfifpollinterval

The larger time interval, in seconds, between the Hello packets sent to an inactive non-broadcast multi-access neighbor

type: int

range: 0..2147483647

config: False

units: seconds

ospfifstate

The OSPF Interface State

type: OspfIfState

config: False

ospfifdesignatedrouter

The IP address of the designated router

type: str

pattern: (([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(%[\p{N}\p{L}]+)?

config: False

ospfifbackupdesignatedrouter

The IP address of the backup designated router

type: str

pattern: (([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(%[\p{N}\p{L}]+)?

config: False

ospfifevents

The number of times this OSPF interface has changed its state or an error has occurred. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ospfDiscontinuityTime

type: int

range: 0..4294967295

config: False

ospfifauthkey

The cleartext password used as an OSPF authentication key when simplePassword security is enabled. This object does not access any OSPF cryptogaphic (e.g., MD5) authentication key under any circumstance. If the key length is shorter than 8 octets, the agent will left adjust and zero fill to 8 octets. Unauthenticated interfaces need no authentication key, and simple password authentication cannot use a key of more than 8 octets. Note that the use of simplePassword authentication is NOT recommended when there is concern regarding attack upon the OSPF system. SimplePassword authentication is only sufficient to protect against accidental misconfigurations because it re-uses cleartext passwords [RFC1704]. When read, ospfIfAuthKey always returns an octet string of length zero

type: str

length: 0..256

config: False

ospfifstatus

This object permits management of the table by facilitating actions such as row creation, construction, and destruction. The value of this object has no effect on whether other objects in this conceptual row can be modified

type: RowStatus

config: False

ospfifmulticastforwarding

The way multicasts should be forwarded on this interface: not forwarded, forwarded as data link multicasts, or forwarded as data link unicasts. Data link multicasting is not meaningful on point-to-point and NBMA interfaces, and setting ospfMulticastForwarding to 0 effectively disables all multicast forwarding

type: OspfIfMulticastForwarding

config: False

ospfifdemand

Indicates whether Demand OSPF procedures (hello suppression to FULL neighbors and setting the DoNotAge flag on propagated LSAs) should be performed on this interface

type: bool

config: False

ospfifauthtype

The authentication type specified for an interface. Note that this object can be used to engage in significant attacks against an OSPF router

type: OspfAuthenticationType

config: False

ospfiflsacount

The total number of link-local link state advertisements in this interface’s link-local link state database

type: int

range: 0..4294967295

config: False

ospfiflsacksumsum

The 32-bit unsigned sum of the Link State Advertisements’ LS checksums contained in this interface’s link-local link state database. The sum can be used to determine if there has been a change in the interface’s link state database and to compare the interface link state database of routers attached to the same subnet

type: int

range: 0..4294967295

config: False

ospfifdesignatedrouterid

The Router ID of the designated router

type: str

pattern: (([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(%[\p{N}\p{L}]+)?

config: False

ospfifbackupdesignatedrouterid

The Router ID of the backup designated router

type: str

pattern: (([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(%[\p{N}\p{L}]+)?

config: False

cospfiflsacount

The total number of link-local link state advertisements in this interface’s link-local link state database

type: int

range: 0..4294967295

config: False

cospfiflsacksumsum

The 32-bit unsigned sum of the link-state advertisements’ LS checksums contained in this interface’s link-local link state database. The sum can be used to determine if there has been a change in the interface’s link state database, and to compare the interface link-state database of routers attached to the same subnet

type: int

range: 0..4294967295

config: False
