PRVT-OSPF-MIB: View SNMP OID List / Download MIB

The PRVT OSPF MIB module contains additional information, needed to control the OSPF protocol, that is not found in the standard RFC

A 32-bit integer uniquely identifying the router in the Autonomous System. By convention, to ensure uniqueness, this should default to the value of one of the router's IP interface addresses.

The administrative status of OSPF in the router. The value 'enabled' denotes that the OSPF Process is active on at least one interface; 'disabled' disables it on all interfaces. Enumeration: 'disabled': 2, 'enabled': 1.

The current version number of the OSPF protocol is 2. Enumeration: 'version2': 2.

The number of external (LS type 5) link-state advertisements in the link-state database.

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.

The router's support for type-of-service routing.

The number of new link-state advertisements that have been originated. This number is incremented each time the router originates a new LSA.

The number of link-state advertisements re- ceived determined to be new instantiations. This number does not include newer instantia- tions of self-originated link-state advertise- ments.

The maximum number of non-default AS- external-LSAs entries that can be stored in the link-state database. If the value is -1, then there is no limit. When the number of non-default AS-external-LSAs in a router's link-state database reaches ospfExtLsdbLimit, the router enters Overflow- State. The router never holds more than ospfExtLsdbLimit non-default AS-external-LSAs in its database. OspfExtLsdbLimit MUST be set identically in all routers attached to the OSPF backbone and/or any regular OSPF area. (i.e., OSPF stub areas and NSSAs are excluded).

A Bit Mask indicating whether the router is forwarding IP multicast (Class D) datagrams based on the algorithms defined in the Multi- cast Extensions to OSPF. Bit 0, if set, indicates that the router can forward IP multicast datagrams in the router's directly attached areas (called intra-area mul- ticast routing). Bit 1, if set, indicates that the router can forward IP multicast datagrams between OSPF areas (called inter-area multicast routing). Bit 2, if set, indicates that the router can forward IP multicast datagrams between Auto- nomous Systems (called inter-AS multicast rout- ing). Only certain combinations of bit settings are allowed, namely: 0 (no multicast forwarding is enabled), 1 (intra-area multicasting only), 3 (intra-area and inter-area multicasting), 5 (intra-area and inter-AS multicasting) and 7 (multicasting everywhere). By default, no mul- ticast forwarding is enabled.

The number of seconds that, after entering OverflowState, a router will attempt to leave OverflowState. This allows the router to again originate non-default AS-external-LSAs. When set to 0, the router will not leave Overflow- State until restarted.

The router's support for demand routing.

Information describing the configured parameters and cumulative statistics of the router's attached areas.

Information describing the configured parameters and cumulative statistics of one of the router's attached areas.

An octet string, uniquely identifying area. Both A.B.C.D or integer notations are supported. Area ID 0.0.0.0 is used for the OSPF backbone.

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.

The area type Enumeration: 'default': 0, 'stub': 1, 'nssa': 2.

The variable ospfAreaSummary controls the im- port of summary LSAs into stub areas. It has no effect on other areas. If it is noAreaSummary, the router will neither originate nor propagate summary LSAs into the stub area. It will rely entirely on its de- fault route. If it is sendAreaSummary, the router will both summarize and propagate summary LSAs. Enumeration: 'sendAreaSummary': 2, 'noAreaSummary': 1.

The authentication type specified for an area. Additional authentication types may be assigned locally on a per Area basis. Enumeration: 'simple': 1, 'md5': 2.

Allows the user to set whether the area allows the traffict to pass through other not backbone area

Transit role Enumeration: 'ospfNssaRoleNever': 0, 'ospfNssaRoleAlways': 1, 'ospfNssaRoleCandidate': 2.

The OSPF Process's Link State Database.

A single Link State Advertisement.

The 32 bit identifier of the Area from which the LSA was received.

The type of the link state advertisement. Each link state type has a separate advertisement format. Enumeration: 'routerLink': 1, 'opaqueAreaLsa': 10, 'asSummaryLink': 4, 'networkLink': 2, 'nssaExternalLink': 7, 'asExternalLink': 5, 'multicastLink': 6, 'summaryLink': 3, 'opaqueAsLsa': 11, 'opaqueLinkLsa': 9, 'unknownLink': 8.

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.

The 32 bit number that uniquely identifies the originating router in the Autonomous System.

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.

This field is the age of the link state advertisement in seconds.

This field is 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.

The length of the ospf packet

The entire Link State Advertisement, including its header.

The OSPF Process's Links State Database.

The OSPF Interface Table describes the inter- faces from the viewpoint of OSPF.

The OSPF Interface Entry describes one inter- face from the viewpoint of OSPF.

The IP address of this OSPF interface.

This variable displays the status of the entry. Setting it to 'invalid' has the effect of rendering it inoperative. The internal effect (row removal) is implementation dependent.

An octet string, uniquely identifying area. Both A.B.C.D or integer notations are supported. Area ID 0.0.0.0 is used for the OSPF backbone.

Working mode Enumeration: 'active': 0, 'passive': 1.

The estimated number of seconds it takes to transmit a link state update packet over this interface.

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.

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.

The number of seconds that a router's Hello packets have not been seen before it's neigh- bors 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.

The number of seconds between link-state ad- vertisement retransmissions, for adjacencies belonging to this interface. This value is also used when retransmitting database descrip- tion and link-state request packets.

A table of non-virtual neighbor information.

The information regarding a single neighbor.

The IP address this neighbor is using in its IP Source Address. Note that, on addressless links, this will not be 0.0.0.0, but the ad- dress of another of the neighbor's interfaces.

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.

A 32-bit integer (represented as a type IpAd- dress) uniquely identifying the neighboring router in the Autonomous System.

A Bit Mask corresponding to the neighbor's op- tions field. Bit 0, 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. Bit 1, if set, indicates that the associated area accepts and operates on external informa- tion; if zero, it is a stub area. Bit 2, if set, indicates that the system is ca- pable of routing IP Multicast datagrams; i.e., that it implements the Multicast Extensions to OSPF. Bit 3, if set, indicates that the associated area is an NSSA. These areas are capable of carrying type 7 external advertisements, which are translated into type 5 external advertise- ments at NSSA borders.

The priority of this neighbor in the designat- ed router election algorithm. The value 0 sig- nifies that the neighbor is not eligible to be- come the designated router on this particular network.

The State of the relationship with this Neigh- bor. Enumeration: 'exchangeStart': 5, 'loading': 7, 'attempt': 2, 'exchange': 6, 'down': 1, 'init': 3, 'full': 8, 'twoWay': 4.

The number of times this neighbor relationship has changed state, or an error has occurred.

The current length of the retransmission queue.

This variable displays the status of the entry. 'dynamic' and 'permanent' refer to how the neighbor became known. Enumeration: 'permanent': 2, 'dynamic': 1.

Indicates whether Hellos are being suppressed to the neighbor

The table represents the routing protocols, redistributed into the OSPF routing domain. Creation of conceptual row in the table starts the redistribution of the specified protocol, which would lead to the injection of routing information from that protocol into the OSPF. Deletion of conceptual row would stop the redistribution of that protocol into the OSPF. OSPF router, which redistributes routing information from other protocols, is an ASBR router

The conceptual row represents a routing protocol, redistributed into OSPF

The specific routes redistributed into OSPF. For T4R model the valid values are connected, rip and static. For all the other models all of the above routes can be redistributed Enumeration: 'default': 17, 'kernel': 2, 'connected': 3, 'static': 4.

Indicates the status of the row. Setting of this field to active enables the redistribution of the protocol. Setting this field to destroy disables the redistribution of the protocol.

Set to 'true' to enable the traffic engineering extensions of OSPF. Note that enabling traffic engineering requires that router interface lo1 (PRVT-SWITCH-IPVLAN-MIB::ipInterfaceIpAddress.lo1) be configured with a valid IP address (not 0.0.0.0 or 127.0.0.1). An attempt to enable traffic engineering without such a valid address will fail (error returned).
