What Is Wellfleet-NHRP-MIB?

Wellfleet-NHRP-MIB is a Wellfleet/Bay Networks (later Nortel) proprietary MIB implementing management for NHRP (Next Hop Resolution Protocol), used to resolve next-hop addresses for shortcut routing across NBMA (non-broadcast multi-access) networks like Frame Relay or ATM. It exposes NHRP cache/network tables tracking layer 2/3 address mappings, resolution request paths, and client registration/timeout behavior. From a monitoring perspective it supports checking NHRP client operational parameters such as registration interval, hold time, request timeout/retry counts, and whether the client is administratively disabled, functioning as a software/protocol-state health indicator for NBMA shortcut-routing services. It implicitly depends on the base NHRP protocol specification (RFC 2332) whose concepts it mirrors in vendor-specific object naming. It is typically deployed on legacy Wellfleet/Bay Networks routers participating in Frame Relay or ATM NBMA clouds, where Wellfleet-NHRP-MIB SNMP monitoring helps confirm NHRP shortcut path resolution is functioning correctly.

IPNetwork Monitor allows you to monitor SNMP objects defined in Wellfleet-NHRP-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

  • Wellfleet/Bay Networks (Nortel) routers on NBMA (Frame Relay/ATM) networks

Monitoring Examples

An administrator would poll wfNhrpNetTable/wfNhrpNetEntry to inspect resolved next-hop mappings, checking wfNhrpLayer2Type and wfNhrpLayer3Type to confirm address-family consistency across NBMA shortcuts. Reading wfNhrpClientDisable alongside wfNhrpClientRegInterval and wfNhrpClientHoldTime reveals whether the NHRP client is active and how aggressively it refreshes registrations; a client with wfNhrpClientDisable set unexpectedly would explain stalled shortcut-path resolution. wfNhrpNHReqPath and the wfNhrpClientReqTimeout/wfNhrpClientReqRetry counters help diagnose slow or failing next-hop resolution requests across the NBMA cloud.

What Can Be Monitored

  • NHRP cache/network table entries
  • layer 2/3 address type mappings
  • client registration interval
  • client hold time
  • request timeout and retry counts
  • client enabled/disabled state
