Description: Enterasys Networks OSPF extension MIB providing supplementary OSPF configuration objects beyond RFC 4750.

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 ENTERASYS-OSPF-EXT-MIB?

This is an Enterasys Networks enterprise MIB that supplements the standard OSPF-MIB (RFC 4750) with vendor-specific OSPF routing protocol tuning and diagnostic objects for Enterasys routers and Layer 3 switches. It exposes configuration data for SPF calculation throttling (delay, threshold, and pause parameters), route selection limits like maximum equal-cost paths, LSA refresh intervals, and external LSA counters. Its primary monitoring value is operational visibility into OSPF process health and load, including external LSA counts and checksums that can reveal database instability or churn, and operational status of the extension itself. It explicitly states it is designed to be used in conjunction with the IETF OSPF-MIB, so full OSPF state (neighbors, areas, interfaces) must be read from that companion MIB. It is deployed in enterprise or service-provider networks running OSPF on Enterasys/Extreme routing platforms where SPF calculation tuning and LSA churn need to be monitored using the ENTERASYS-OSPF-EXT-MIB MIB.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-OSPF-EXT-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

Enterasys (Extreme Networks) enterprise routers/Layer 3 switches

Monitoring Examples

An administrator would poll etsysOspfExtExternOpLsaCount and etsysOspfExtExternOpLsaCksumSum to track external LSA volume and detect unexpected route redistribution churn or a routing loop injecting excess external routes. Checking etsysOspfExtCalcThrshIncUpdates and etsysOspfExtCalcPauseFreq against etsysOspfExtOperStatus helps confirm whether SPF throttling parameters are active and tuned correctly during periods of topology instability, and etsysOspfExtRteMaxEqCostPaths confirms the configured ECMP path limit is being honored.

What Can Be Monitored

OSPF extension operational status
SPF calculation throttle timers
external LSA count and checksum sum
maximum equal-cost route paths
LSA refresh interval

How to Use in IPNetwork Monitor

Example using etsysOspfExtExternOpLsaCount OID:

Select an Enterasys Networks router/Layer 3 switch (legacy, later Extreme Networks) (OSPF SPF tuning/LSA diagnostics) 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 etsysOspfExtExternOpLsaCount into the Find box to locate it in the OID tree, then select it and click OK. The number of type-11 LSAs in the external database. 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 Gauge32-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.

etsysOspfExtAreaTable	1.3.6.1.4.1.5624.1.2.65.1.2.1		not-accessible	This table provides additional information pertaining to OSPF Areas for Enterasys OSPF systems.
T/F etsysOspfExtAreaTransitCapability	1.3.6.1.4.1.5624.1.2.65.1.2.1.1.3	TruthValue	read-only	This parameter indicates whether the area can carry data traffic that neither originates nor terminates in the area itself. This parameter is calculated when the area's shortest-path tree is built.
U32 etsysOspfExtCalcMaxDelay	1.3.6.1.4.1.5624.1.2.65.1.1.2	Unsigned32	read-write	The maximum delay before the Routing Table is recalculated following a change to the Link State Database. (Recalculation is delayed to reduce the frequency of recalculations of the Routing Table). This parameter has units of milliseconds. A value of 0 indicates that a routing calculation will immediately follow an update to the database.
I32 etsysOspfExtCalcPauseFreq	1.3.6.1.4.1.5624.1.2.65.1.1.7	Integer32	read-write	This value determines how regularly a Routing Calculation is paused. It is measured in points. The points scale roughly maps to a time scale, so that the larger this value is, the longer the Routing Calculation runs before pausing. -1 Indicates that the Routing Calculation is never paused. 0 Indicates that the routing calculation is paused after every calculation step.
I32 etsysOspfExtCalcThrshIncSpfUpd	1.3.6.1.4.1.5624.1.2.65.1.1.6	Integer32	read-write	This parameter can be used to optimize the performance of the Routing Calculator in the situation where updates that are pending to the Link State Database concern intra-area routes. In this case, the Routing Table can be updated either by one full recalculation, or by multiple incremental SPF recalculations. This parameter is used to configure the threshold value for which recalculation by multiple incremental SPF updates is no longer quicker than a single full recalculation. -1 Indicates that this threshold is infinite, and incremental SPF recalculations are always done in preference to a full recalculation. 0 Indicates that incremental SPF updates will never be used. 1..2147483647 (n) Indicates that a full recalculation will be performed whenever there are more than 'n' updates to make to intra-area routes.
I32 etsysOspfExtCalcThrshIncUpdates	1.3.6.1.4.1.5624.1.2.65.1.1.5	Integer32	read-write	This parameter can be used to optimize the performance of the Routing Calculator in the situation where updates that are pending to the Link State Database solely concern inter-area or AS-external routes. In this case, the Routing Table can be updated either by one full recalculation, or by multiple incremental recalculations. This parameter is used to configure the threshold value for which recalculation by multiple incremental updates is no longer quicker than a single full recalculation. -1 Indicates that this threshold is infinite, and incremental recalculations are always done in preference to a full recalculation. 0 Indicates that incremental updates will never be used. 1..2147483647 (n) Indicates that a full recalculation will be performed whenever there are more than 'n' updates to make to inter-area or AS-external routes.
I32 etsysOspfExtCalcThrshUpdRestart	1.3.6.1.4.1.5624.1.2.65.1.1.4	Integer32	read-write	This parameter can be used to interrupt a full routing calculation when the number of pending updates to the Link State Database has reached a threshold value. -1 Indicates that this threshold is infinite, and hence no number of pending updates to the database will cause a routing calculation to be interrupted. 0 Indicates that an update to the Link State Database will cause any current routing calculation to be interrupted and a new one to start. 1..2147483647 Specifies the threshold number of updates that can be made to the Link State Database such that any subsequent update to the database causes the current routing calculation to be interrupted, and a new calculation to start using an up to date Link State Database.
I32 etsysOspfExtCalcThrshUpdStart	1.3.6.1.4.1.5624.1.2.65.1.1.3	Integer32	read-write	This parameter can be used to override the etsysOspfExtCalcMaxDelay when the number of updates to the Link State Database reaches a threshold value. -1 Indicates that this threshold is infinite, and hence the timing of a routing calculation is determined solely by etsysOspfExtCalcMaxDelay. 0 Indicates that a routing calculation will immediately follow an update to the database. 1..2147483647 Specifies the threshold number of updates that can be made to the Link State Database such that any subsequent update to the database causes a full routing calculation to start immediately.
U32 etsysOspfExtCheckAge	1.3.6.1.4.1.5624.1.2.65.1.1.9	Unsigned32	read-write	This value determines how often the checksums of LSAs in the Link State Database are checked. If 0, no checksums in the database are checked.
etsysOspfExtCompliance	1.3.6.1.4.1.5624.1.2.65.2.2.1			The compliance statement for devices that support etsysOspfExt.
etsysOspfExtCompliances	1.3.6.1.4.1.5624.1.2.65.2.2
etsysOspfExtConformance	1.3.6.1.4.1.5624.1.2.65.2
T/F etsysOspfExtDoGraceHitless	1.3.6.1.4.1.5624.1.2.65.1.1.16	TruthValue	read-write	Indicates whether OSPF should perform hitless restart using grace LSAs. If OSPF is being deactivated, grace LSAs are sent out to inform neighboring routers that we wish to undergo a hitless restart. If OSPF is being activated, we will attempt to restart hitlessly, then set this field to 'false'. Therefore this field needs to be explicitly set to 'true' each time planned hitless restart is required. This object is persistent and when written the entity SHOULD save the change to non-volatile storage.
T/F etsysOspfExtDoGraceUnplannedHitless	1.3.6.1.4.1.5624.1.2.65.1.1.17	TruthValue	read-write	Indicates whether OSPF should perform an unplanned hitless restart using grace LSAs. Note that etsysOspfExtDoGraceHitless has a higher priority than this object. Therefore if both etsysOspfExtDoGraceHitless and this object are both set to 'true' on activation, OSPF will assume it is undergoing a planned hitless restart. If only this object is 'true', then OSPF will attempt an unplanned hitless restart, and send out grace LSAs on activation.
U32 etsysOspfExtExternOpLsaCksumSum	1.3.6.1.4.1.5624.1.2.65.1.1.12	Unsigned32	read-only	The 32 bit sum of LS checksums of all type-11 LSAs in the external Link State Database.

U32 etsysOspfExtExtLsaRfshIntvl	1.3.6.1.4.1.5624.1.2.65.1.1.10	Unsigned32	read-write	Self-originated LSAs are periodically reflooded into the routing domain to add to the robustness of the OSPF protocol. This value determines the interval between refreshes of type-5 and type-11 AS-external LSAs, and is defaulted to the OSPF standard default of 1800 seconds (30 minutes).
etsysOspfExtGlobalGroup	1.3.6.1.4.1.5624.1.2.65.2.1.1			This group defines global controls for Enterasys OSPF systems.
etsysOspfExtGlobals	1.3.6.1.4.1.5624.1.2.65.1.1
etsysOspfExtGroups	1.3.6.1.4.1.5624.1.2.65.2.1
U32 etsysOspfExtHitlessGracePeriod	1.3.6.1.4.1.5624.1.2.65.1.1.18	Unsigned32	read-write	If OSPF is attempting to undergo a hitless restart, this field specifies the length of grace period that should be requested from adjacent routers in grace LSAs. After this timer period has passed, an RTM will delete routes from this RPM from its routing table, and so hitless restart will have failed. Hitless grace period must be greater than zero.
OCT etsysOspfExtIfAuthUserData	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.9	OCTET STRING	read-create	Authentication user data for interface level authentication. This data is passed opaquely to the authentication process, where it can be used to assist with authentication decisions. When read, etsysOspfExtIfAuthUserData always returns an Octet String of length zero.
T/F etsysOspfExtIfAutoDeleteNbr	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.11	TruthValue	read-create	Whether dynamically created entries in the ospfNbrTable should be kept when the adjacency goes down. If this object is set to 'false', then a dynamically created entry in the ospfNbrTable will remain with state 'down' when the adjacency is lost. Such entries can be deleted manually by setting ospfNbrStatus to 'destroy'. If this object is set to 'true', then dynamically created entries in the ospfNbrTable will be deleted automatically when the adjacency goes down.
etsysOspfExtIfEntry	1.3.6.1.4.1.5624.1.2.65.1.2.2.1		not-accessible	An entry (conceptual row) in the etsysOspfExtIfTable.
U32 etsysOspfExtIfFastHelloMultiplier	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.10	Unsigned32	read-create	The number of Hellos that should be sent within 1 second when using Fast Hellos on this interface. This value does not have to be same for all routers attached to a common network, but it is advisable. Fast Hellos are configured using ospfIfRtrDeadInterval.
etsysOspfExtIfGroup	1.3.6.1.4.1.5624.1.2.65.2.1.3			This group defines the additional OSPF Interface objects supported in the Enterasys OSPF systems.
BIT etsysOspfExtIfHelperModePolicy	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.7	Bits	read-create	Indicates whether OSPF will help a neighbor undergoing hitless restart on this interface for the specified reason. This field contains a bit flag for each of OspfHitlessRestartReasons. If a bit flag for a specific restart reason is set, then OSPF will help a router restarting for this reason. Otherwise grace LSAs received containing this restart reason will be ignored.
U32 etsysOspfExtIfIPMaxPacketSize	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.4	Unsigned32	read-create	Maximum transfer unit (MTU) for the network interface. This is the maximum packet size in bytes for packets sent over the network interface. This size excludes link layer headers but includes IP headers and higher-level headers. Normally, OSPF limits sent PDUs (protocol data units) to less than or equal to this size. However, if OSPF cannot construct a valid PDU smaller than or equal to this size, then it will send the smallest valid PDU and assume that the IP stack will fragment the packet.
U32 etsysOspfExtIfLsaRefreshIntvl	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.6	Unsigned32	read-create	Self-originated LSAs are periodically reflooded into the routing domain, to add to the robustness of the OSPF protocol. This value determines the interval between refreshes of LSAs that are only flooded over this interface (type-9 opaque LSAs) and is defaulted to the OSPF standard default of 1800 seconds (30 minutes).
U32 etsysOspfExtIfMaxHitlessGracePeriod	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.8	Unsigned32	read-create	If configured to help neighbors undergoing hitless restart on this interface, this field indicates the maximum grace period that will be allowed for a neighboring router undergoing hitless restart. If a type-9 grace LSA is received with a greater requested grace period, then the grace LSA will be ignored.
T/F etsysOspfExtIfMtuIgnore	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.12	TruthValue	read-create	This object controls whether OSPF checks the MTU size on incoming Database Description packets. By default, if the received MTU size in a DB Description packet is higher than the MTU size configured on the incoming interface, the OSPF adjacency will not be established. If the interface is tunneled over, say, an MPLS network, then the administrator may not know the maximum MTU size and so can tell OSPF to ignore the MTU size on incoming DB description packets.
IP etsysOspfExtIfNetMask	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.2	IpAddress	read-create	The subnet mask associated with the IP address of this entry. The value of the mask is an IP address with all the network bits set to 1 and all the hosts bits set to 0.
ETS etsysOspfExtIfOperStatus	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.1	EtsysOspfOperStatus	read-only	The current operational state of OSPF on this interface.
T/F etsysOspfExtIfPassive	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.5	TruthValue	read-create	Indicates whether this interface is a passive interface. If set to 'true', we suppress HELLO packets sent on and received from this interface. We will therefore advertise this interface in our LSAs but not run the OSPF protocol over it.
etsysOspfExtIfTable	1.3.6.1.4.1.5624.1.2.65.1.2.2		not-accessible	This table provides additional information pertaining to OSPF Interfaces for Enterasys OSPF systems.
U32 etsysOspfExtIfTransmitTimerDelay	1.3.6.1.4.1.5624.1.2.65.1.2.2.1.3	Unsigned32	read-create	The time this interface will delay a LSU packet, in order to add more LSAs to the packet before sending. Setting this correctly can reduce the network traffic. This is configurable on a per-interface basis.
ARE etsysOspfExtLocalLsdbAreaId	1.3.6.1.4.1.5624.1.2.65.1.2.6.1.1	AreaID	read-only	The OSPF area in which the link belongs.
etsysOspfExtLocalLsdbEntry	1.3.6.1.4.1.5624.1.2.65.1.2.6.1		not-accessible	An entry (conceptual row) in the etsysOspfExtLocalLsdbTable.

etsysOspfExtLocalLsdbTable	1.3.6.1.4.1.5624.1.2.65.1.2.6		not-accessible	This table provides additional information pertaining to OSPF Local LS Database for Enterasys OSPF systems.
etsysOspfExtMIB	1.3.6.1.4.1.5624.1.2.65			This MIB module defines a portion of the SNMP MIB under the Enterasys Networks enterprise OID pertaining to the OSPF configuration. This MIB was designed to be used in conjunction with the OSPF-MIB (RFC 4750) for configuring the OSPF protocol parameters.
STA etsysOspfExtNbrAdminStatus	1.3.6.1.4.1.5624.1.2.65.1.2.4.1.1	Status	read-create	The desired administrative state of this neighbor. When the status of this object is set to 'disabled', the connection to the neighbor is torn down and the routes learned from this neighbor are removed from the RIB. When the status of this object is set to 'enabled', the connection to the neighbor is established (if possible) and routes learned from the neighbor are added to the RIB.
ARE etsysOspfExtNbrAreaId	1.3.6.1.4.1.5624.1.2.65.1.2.4.1.6	AreaID	read-only	The area to which the neighbor belongs. If the etsysOspfExtNbrOperStatus is down, then this value is set to zero and the field is not valid.
U32 etsysOspfExtNbrDeadTime	1.3.6.1.4.1.5624.1.2.65.1.2.4.1.5	Unsigned32	read-only	The time remaining in seconds within which we need to receive a hello packet from the neighbor or we declare the adjacency down. If fast hellos area in use, this value is always set to 1. If the etsysOspfExtNbrOperStatus is down or ospfNbrState is DOWN, then the value is set to zero and the field is not valid.
etsysOspfExtNbrEntry	1.3.6.1.4.1.5624.1.2.65.1.2.4.1		not-accessible	An entry (conceptual row) in the etsysOspfExtNbrTable.
etsysOspfExtNbrGroup	1.3.6.1.4.1.5624.1.2.65.2.1.5			This group defines the additional OSPF Neighbor objects supported in the Enterasys OSPF systems.
IP etsysOspfExtNbrIfIpAddr	1.3.6.1.4.1.5624.1.2.65.1.2.4.1.4	IpAddress	read-create	The IP address of the interface used for this neighbor. If this value is set to zero OSPF will choose a suitable interface to use. If this value is non-zero this neighbor will only be associated with an exactly matching interface. Note this field is only used for NBMA and P2MP links. Also, the etsysOspfExtNbrAdminStatus object must be 'disabled' prior to modifiying this object.
G32 etsysOspfExtNbrNumRequests	1.3.6.1.4.1.5624.1.2.65.1.2.4.1.3	Gauge32	read-only	The number of LSAs requested from this neighbor for which we are awaiting for a response. This field is incremented when an LSA is requested by sending a LS request packet and is decremented when the LSA arrives in a LS update packet.
ETS etsysOspfExtNbrOperStatus	1.3.6.1.4.1.5624.1.2.65.1.2.4.1.2	EtsysOspfOperStatus	read-only	The current operational state of this neighbor.

ETS etsysOspfExtOperStatus	1.3.6.1.4.1.5624.1.2.65.1.1.1	EtsysOspfOperStatus	read-only	The current operational state of the OSPF Protocol. Changing the state of the ospfAdminStat object effects the state of this object. If ospfAdminStat is set to 'disabled', this object's status is changed to 'operStatusGoingDown'. Once all of the resources have been reclaimed, the status is changed to 'operStatusDown'. If ospfAdminStat is set to 'enabled', this object's status is changed to 'operStatusGoingUp'. When the OSPF protocol has finished the activation process, the state of this object changes to 'operStatusUp'. If there are problems activating the OSPF protocol, the status becomes 'operStatusActFailed'.
U32 etsysOspfExtRteMaxEqCostPaths	1.3.6.1.4.1.5624.1.2.65.1.1.8	Unsigned32	read-write	The maximum number of equal cost paths that are stored for each destination in the Routing Table.
etsysOspfExtTables	1.3.6.1.4.1.5624.1.2.65.1.2
STA etsysOspfExtVirtIfAdminStatus	1.3.6.1.4.1.5624.1.2.65.1.2.3.1.1	Status	read-create	The desired administrative state of this virtual interface. When the status of this object is set to 'disabled', the virtual link is torn down and no routing information is exchanged with its peer. When the status of this object is set to 'enabled', the virtual link is established (if possible) and routing information is shared with its peer. The etsysOspfExtVirtIfOperStatus object provides the status of this connection.
etsysOspfExtVirtIfEntry	1.3.6.1.4.1.5624.1.2.65.1.2.3.1		not-accessible	An entry (conceptual row) in the etsysOspfExtVirtIfTable.
U32 etsysOspfExtVirtIfFastHelloMultiplier	1.3.6.1.4.1.5624.1.2.65.1.2.3.1.9	Unsigned32	read-create	The number of Hellos that should be sent within 1 second when using Fast Hellos on this interface. This value does not have to be same for all routers attached to a common network, but it is advisable. Fast Hellos are configured using ospfVirtIfRtrDeadInterval.
etsysOspfExtVirtIfGroup	1.3.6.1.4.1.5624.1.2.65.2.1.4			This group defines the additional OSPF Virtual Interface objects supported in the Enterasys OSPF systems.
BIT etsysOspfExtVirtIfHelperModePolicy	1.3.6.1.4.1.5624.1.2.65.1.2.3.1.7	Bits	read-create	Indicates whether OSPF will help a neighbor undergoing hitless restart on this interface for the specified reason. This field contains a bit flag for each of OspfHitlessRestartReasons. If a bit flag for a specific restart reason is set, then OSPF will help a router restarting for this reason. Otherwise grace LSAs received containing this restart reason will be ignored.
U32 etsysOspfExtVirtIfIPMaxPacketSize	1.3.6.1.4.1.5624.1.2.65.1.2.3.1.4	Unsigned32	read-create	Maximum transfer unit (MTU) for the network interface. This is the maximum packet size in bytes for packets sent over the network interface. This size excludes link layer headers but includes IP headers and higher-level headers. Normally, OSPF limits sent PDUs (protocol data units) to less than or equal to this size. However, if OSPF cannot construct a valid PDU smaller than or equal to this size, then it will send the smallest valid PDU and assume that the IP stack will fragment the packet.
U32 etsysOspfExtVirtIfLsaRefreshIntvl	1.3.6.1.4.1.5624.1.2.65.1.2.3.1.6	Unsigned32	read-create	Self-originated LSAs are periodically reflooded into the routing domain, to add to the robustness of the OSPF protocol. This value determines the interval between refreshes of LSAs that are only flooded over this interface (type-9 opaque LSAs) and is defaulted to the OSPF standard default of 1800 seconds (30 minutes).
U32 etsysOspfExtVirtIfMaxHtlssGracePeriod	1.3.6.1.4.1.5624.1.2.65.1.2.3.1.8	Unsigned32	read-create	If configured to help neighbors undergoing hitless restart on this interface, this field indicates the maximum grace period that will be allowed for a neighboring router undergoing hitless restart. If a type-9 grace LSA is received with a greater requested grace period, then the grace LSA will be ignored.
T/F etsysOspfExtVirtIfMtuIgnore	1.3.6.1.4.1.5624.1.2.65.1.2.3.1.10	TruthValue	read-create	This object controls whether OSPF checks the MTU size on incoming Database Description packets. By default, if the received MTU size in a DB Description packet is higher than the MTU size configured on the incoming interface, the OSPF adjacency will not be established. If the interface is tunneled over, say, an MPLS network, then the administrator may not know the maximum MTU size and so can tell OSPF to ignore the MTU size on incoming DB description packets.
ETS etsysOspfExtVirtIfOperStatus	1.3.6.1.4.1.5624.1.2.65.1.2.3.1.2	EtsysOspfOperStatus	read-only	The current operational state of OSPF on this virtual interface.
T/F etsysOspfExtVirtIfPassive	1.3.6.1.4.1.5624.1.2.65.1.2.3.1.5	TruthValue	read-create	Indicates whether this interface is a passive interface. If set to 'true', we suppress HELLO packets sent on and received from this interface. We will therefore advertise this interface in our LSAs but not run the OSPF protocol over it.
etsysOspfExtVirtIfTable	1.3.6.1.4.1.5624.1.2.65.1.2.3		not-accessible	This table provides additional information pertaining to OSPF Virtual Interfaces for Enterasys OSPF systems.
U32 etsysOspfExtVirtIfTransmitTimerDelay	1.3.6.1.4.1.5624.1.2.65.1.2.3.1.3	Unsigned32	read-create	The time this interface will delay a LSU packet, in order to add more LSAs to the packet before sending. Setting this correctly can reduce the network traffic. This is configurable on a per-interface basis.
U32 etsysOspfExtVirtNbrDeadTime	1.3.6.1.4.1.5624.1.2.65.1.2.5.1.2	Unsigned32	read-only	The time remaining in seconds within which we need to receive a hello packet from the neighbor or we declare the adjacency down. If fast hellos area in use, this value is always set to 1.
etsysOspfExtVirtNbrEntry	1.3.6.1.4.1.5624.1.2.65.1.2.5.1		not-accessible	An entry (conceptual row) in the etsysOspfExtVirtNbrTable.
etsysOspfExtVirtNbrGroup	1.3.6.1.4.1.5624.1.2.65.2.1.6			This group defines the additional OSPF Virtual Neighbor objects supported in the Enterasys OSPF systems.
G32 etsysOspfExtVirtNbrNumRequests	1.3.6.1.4.1.5624.1.2.65.1.2.5.1.1	Gauge32	read-only	The number of LSAs requested from this neighbor for which we are awaiting for a response. This field is incremented when an LSA is requested by sending a LS request packet and is decremented when the LSA arrives in an LS update packet.
etsysOspfExtVirtNbrTable	1.3.6.1.4.1.5624.1.2.65.1.2.5		not-accessible	This table provides additional information pertaining to OSPF Virtual Neighbors for Enterasys OSPF systems.
