Description: Monitors OSPF neighbor adjacency, link-state database, and area configuration on Juniper NetScreen ScreenOS.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is NETSCREEN-OSPF-MIB?

NETSCREEN-OSPF-MIB is a Juniper NetScreen (ScreenOS firewall/security appliance) vendor MIB describing the OSPFv2 routing protocol implementation running on NetScreen devices. Based on its stated purpose it would expose OSPF protocol state such as neighbor adjacency status, link-state database entries, and area configuration, though no specific sample object names were provided in the available source. It functions primarily as a routing-protocol software-status MIB: it would let an administrator verify OSPF neighbor adjacency and area configuration to confirm the routing protocol is operating correctly on the firewall, rather than exposing any physical hardware sensor data. It is explicitly modeled on the standard OSPF-MIB (RFC 1850/RFC 4750) adapted for NetScreen's ScreenOS implementation. It is deployed on Juniper NetScreen firewall/security appliances participating in OSPF-routed enterprise or service-provider networks, and administrators can download the NETSCREEN-OSPF-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NETSCREEN-OSPF-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Juniper NetScreen firewall/security appliance

Monitoring Examples

No sample object names were provided for this module, so a concrete polling scenario citing specific tables cannot be honestly constructed. Based on the module description and its modeling on the standard OSPF-MIB, it would be expected to include neighbor and area tables analogous to ospfNbrTable and ospfAreaTable, which an administrator would poll to detect a stuck or dropped OSPF adjacency on the firewall.

What Can Be Monitored

OSPF neighbor adjacency state
OSPF area configuration
link-state database entries

OID symbolic	OID numeric	Type	Access	Description
nsOspf	1.3.6.1.4.1.3224.18.2			The MIB module to describe the NS-OSPF Version 2 Protocol
nsOspfGeneralTable	1.3.6.1.4.1.3224.18.2.1		not-accessible	Ospf general information table per VR
nsOspfGeneralEntry	1.3.6.1.4.1.3224.18.2.1.1		not-accessible	Ospf general information table per VR
ROU nsOspfRouterId	1.3.6.1.4.1.3224.18.2.1.1.1	RouterID	read-only	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.
STA nsOspfAdminStat	1.3.6.1.4.1.3224.18.2.1.1.2	Status	read-only	The administrative status of OSPF in the router. The value 'enabled' denotes that the OSPF Process is active on at least one inter- face; 'disabled' disables it on all inter- faces.
INT nsOspfVersionNumber	1.3.6.1.4.1.3224.18.2.1.1.3	INTEGER	read-only	The deprecated version number of the OSPF proto- col is 2.
T/F nsOspfAreaBdrRtrStatus	1.3.6.1.4.1.3224.18.2.1.1.4	TruthValue	read-only	A flag to note whether this router is an area border router.
T/F nsOspfASBdrRtrStatus	1.3.6.1.4.1.3224.18.2.1.1.5	TruthValue	read-only	A flag to note whether this router is config- ured as an Autonomous System border router.
G32 nsOspfExternLsaCount	1.3.6.1.4.1.3224.18.2.1.1.6	Gauge32	read-only	The number of external (LS type 5) link-state advertisements in the link-state database.
I32 nsOspfExternLsaCksumSum	1.3.6.1.4.1.3224.18.2.1.1.7	Integer32	read-only	The 32-bit unsigned sum of the LS checksums of the external link-state advertisements con- tained 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.
T/F nsOspfTOSSupport	1.3.6.1.4.1.3224.18.2.1.1.8	TruthValue	read-only	The router's support for type-of-service rout- ing.
C32 nsOspfOriginateNewLsas	1.3.6.1.4.1.3224.18.2.1.1.9	Counter32	read-only	The number of new link-state advertisements that have been originated. This number is in- cremented each time the router originates a new LSA.
C32 nsOspfRxNewLsas	1.3.6.1.4.1.3224.18.2.1.1.10	Counter32	read-only	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.

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 nsOspfExtLsdbLimit, the router enters Overflow- State. The router never holds more than nsOspfExtLsdbLimit 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).
I32 nsOspfMulticastExtensions	1.3.6.1.4.1.3224.18.2.1.1.12	Integer32	read-only	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.
NUM nsOspfExitOverflowInterval	1.3.6.1.4.1.3224.18.2.1.1.13	PositiveInteger	read-only	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.

This sum excludes external (LS type 5) link-state advertisements.

INT nsOspfAreaSummary	1.3.6.1.4.1.3224.18.2.2.1.9	INTEGER	read-create	The variable nsOspfAreaSummary 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.

BIG nsOspfStubMetric	1.3.6.1.4.1.3224.18.2.3.1.3	BigMetric	read-create	The metric value applied at the indicated type of service. By default, this equals the least metric at the type of service among the inter- faces to other areas.
ROW nsOspfStubStatus	1.3.6.1.4.1.3224.18.2.3.1.4	RowStatus	read-create	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.

Used in multi-access networks, this field is used in the designated router election algorithm.

If the Area's Author- ization Type is simplePassword, and the key length is shorter than 8 octets, the agent will left adjust and zero fill to 8 octets. Note that unauthenticated interfaces need no authentication key, and simple password authen- tication cannot use a key of more than 8 oc- tets. Larger keys are useful only with authen- tication mechanisms not specified in this docu- ment. When read, nsOspfIfAuthKey always returns an Oc- tet String of length zero.
