Description: Provides access to the OSPF link-state database for topology and LSA inspection.

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 RADLAN-OSPF-LSDB-MIB?

RADLAN-OSPF-LSDB-MIB is a vendor-specific private MIB from RADLAN/Marvell that gives read access into a device's OSPF Link-State Database, exposing the raw Link-State Advertisements a router has learned. It defines tables such as rlOspfRouterLsaTable/Entry with fields for process ID, area ID, link-state ID, originating router ID, sequence number, age, checksum, and length. This is primarily a software/protocol-state monitoring tool: it lets an operator verify OSPF topology convergence, confirm an LSA hasn't gone stale (via rlOspfRouterLsaAge) or become corrupted (via a checksum mismatch), and detect routers missing from the expected topology. It extends and depends on the standard OSPF protocol and the concepts defined in the standard OSPF-MIB, providing vendor-specific detail beyond it. It is typically deployed on Marvell/RADLAN-based Layer 3 switches or routers running OSPF within an enterprise or service-provider network. Engineers can download the RADLAN-OSPF-LSDB-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RADLAN-OSPF-LSDB-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.

Monitoring Examples

An administrator would walk rlOspfRouterLsaTable, keyed by rlOspfRouterLsaProcessId, rlOspfRouterLsaAreaId, and rlOspfRouterLsaLsid, to inspect rlOspfRouterLsaAge and rlOspfRouterLsaSequence for a given rlOspfRouterLsaRouterId, spotting an LSA that is aging toward MaxAge without being refreshed, which signals a router that has dropped out of the OSPF topology. rlOspfRouterLsaChecksum can also be compared to detect corrupted or stale link-state data.
