- ospfOriginateNewLsas, ospfRxNewLsas in the ospfGeneralGroup - ospfOriginateNewLsas, ospfRxNewLsas in the ospfGeneralGroup
- ospfSpfRuns, ospfAreaNssaTranslatorEvents in the ospfAreaTable - ospfSpfRuns, ospfAreaNssaTranslatorEvents in the ospfAreaTable

- ospfNbrEvents in the ospfNbrTable - ospfNbrEvents in the ospfNbrTable
- ospftVirtNbrEvents in the ospfVirtNbrEvents. - ospfVirtNbrEvents in the ospfVirtNbrTable
As a best practice, a management entity, when reading these
counters, should use the discontinuity object,
ospfDiscontinuityTime, to determine if an event which would
invalidate the management entity understanding of the counters has
occurred. A restart of the OSPF routing process is a possible
example of a discontinuity event.
1.5 Multiple OSPF Instances As a best practice, a management entity, when reading these counters,
should use the discontinuity object, ospfDiscontinuityTime, to
determine if an event that would invalidate the management entity
understanding of the counters has occurred. A restart of the OSPF
routing process is a possible example of a discontinuity event.

variables that are global to the OSPF Process.
The Area Data Structure describes all of the OSPF Areas that the 2.1.2. Area Data Structure and Area Stub Metric Table
router participates in. The Area Table includes data for NSSA
translation.
The Area Stub Metric Table describes the metrics advertised into The Area Data Structure describes all of the OSPF Areas that the

2.1.6 Virtual Interface Table The Interface Table and the Interface Metric Table together describe
the various IP interfaces to OSPF. The metrics are placed in
separate tables in order to simplify dealing with multiple types of
service. The Interface table includes link-local (Opaque type-9)
link state advertisement (LSA) statistics.
The Virtual Interface Table describes virtual links to the 2.1.6. Virtual Interface Table
OSPF Process, similarly to the (non-Virtual)Interface Tables. This
table includes Link-Local (Opaque Type-9) LSA statistics.
2.1.7 Neighbor and Virtual Neighbor Tables The Virtual Interface Table describes virtual links to the OSPF
Process, similarly to the (non-virtual) Interface Tables. This Table
includes link-local (Opaque type-9) LSA statistics.
The Neighbor Table and the Virtual Neighbor Table describe the 2.1.7. Neighbor and Virtual Neighbor Tables
