Description: Monitors OSPF routing state within virtual router contexts on Juniper NetScreen ScreenOS firewalls.

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-VR-OSPF-MIB?

NETSCREEN-VR-OSPF-MIB is a Juniper NetScreen (ScreenOS) vendor MIB describing the NetScreen implementation of OSPF version 2 as it runs within a virtual router (VR) context. No sample objects were available in this entry, so specifics beyond the stated purpose cannot be confirmed. In general such a MIB would expose OSPF area, interface, and neighbor state scoped per virtual router, mirroring the structure of the standard OSPF MIB (RFC 1850/OSPF-MIB) but applied within NetScreen's VR model. Its monitoring value would be software/protocol status: tracking neighbor adjacency state and area configuration to detect OSPF adjacency failures or misconfiguration within a given VR. It clearly depends on both the standard OSPF-MIB conventions and the NetScreen virtual-router (NETSCREEN-VR-MIB) framework for its per-VR scoping. It would be deployed on Juniper NetScreen firewalls using OSPF as their dynamic routing protocol within one or more virtual routers. Engineers can download the NETSCREEN-VR-OSPF-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NETSCREEN-VR-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 (OSPF within virtual router)

Monitoring Examples

No sample objects were provided for this MIB, so a concrete object-level monitoring scenario cannot be honestly constructed; in general, an administrator would expect to poll OSPF neighbor and interface state scoped to a specific virtual router to detect adjacency loss or area misconfiguration, analogous to the standard OSPF-MIB.

How to Use in IPNetwork Monitor

Example using nsVrOspfOriginateNewLsas OID:

Select a Juniper NetScreen firewall (OSPFv2 within virtual router) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type nsVrOspfOriginateNewLsas into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of new link-state advertisements that have been originated. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OID symbolic	OID numeric	Type	Access	Description
nsVrOspf	1.3.6.1.4.1.3224.18.5			The MIB module to describe the NS-OSPF Version 2 Protocol
nsVrOspfGeneralTable	1.3.6.1.4.1.3224.18.5.1		not-accessible	Ospf general information table per VR
nsVrOspfGeneralEntry	1.3.6.1.4.1.3224.18.5.1.1		not-accessible	Ospf general information table per VR
ROU nsVrOspfRouterId	1.3.6.1.4.1.3224.18.5.1.1.1	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 nsVrOspfAdminStat	1.3.6.1.4.1.3224.18.5.1.1.2	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 nsVrOspfVersionNumber	1.3.6.1.4.1.3224.18.5.1.1.3	INTEGER	read-only	The current version number of the OSPF proto- col is 2.
T/F nsVrOspfAreaBdrRtrStatus	1.3.6.1.4.1.3224.18.5.1.1.4	TruthValue	read-only	A flag to note whether this router is an area border router.
T/F nsVrOspfASBdrRtrStatus	1.3.6.1.4.1.3224.18.5.1.1.5	TruthValue	read-only	A flag to note whether this router is config- ured as an Autonomous System border router.

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 nsVrOspfTOSSupport	1.3.6.1.4.1.3224.18.5.1.1.8	TruthValue	read-only	The router's support for type-of-service rout- ing.

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 nsVrOspfExtLsdbLimit, the router enters Overflow- State. The router never holds more than nsVrOspfExtLsdbLimit 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 nsVrOspfMulticastExtensions	1.3.6.1.4.1.3224.18.5.1.1.12	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 nsVrOspfExitOverflowInterval	1.3.6.1.4.1.3224.18.5.1.1.13	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. The sum can be used to determine if there has been a change in a router's link state data- base, and to compare the link-state database of two routers.
INT nsVrOspfAreaSummary	1.3.6.1.4.1.3224.18.5.2.1.9	INTEGER	read-create	The variable nsVrOspfAreaSummary 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 nsVrOspfStubMetric	1.3.6.1.4.1.3224.18.5.3.1.3	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 nsVrOspfStubStatus	1.3.6.1.4.1.3224.18.5.3.1.4	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.

Broad- cast 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'.

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, nsVrOspfIfAuthKey always returns an Oc- tet String of length zero.
