Description: MPLS-FRR-STD-MIB module

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 MPLS-FRR-STD-MIB?

MPLS-FRR-STD-MIB is an IETF standards-track module (RFC 4327) defining managed objects for MPLS Traffic Engineering Fast Reroute (FRR) as specified in RFC 4090, the mechanism that provides sub-second local protection for MPLS TE tunnels via pre-established backup (bypass/detour) LSPs. A module of this kind exposes configuration and status for protected tunnels, backup-tunnel association, and switchover state, though no object list survived in this excerpt. Monitoring emphasis is on fault/failover status: whether a primary LSP has switched to its backup path, protection availability, and switchover events - key indicators of MPLS network resilience. It explicitly extends the MPLS-TE-STD-MIB (RFC 3812) for base traffic-engineering tunnel objects. Typical deployment is service-provider MPLS core/backbone routers implementing fast-reroute protection for TE tunnels, per the MPLS-FRR-STD-MIB RFC that defines these managed objects.

IPNetwork Monitor allows you to monitor SNMP objects defined in MPLS-FRR-STD-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

  • vendor-neutral, standards-based MIB, not tied to a specific manufacturer
  • MPLS-TE-capable service-provider router

Monitoring Examples

No sample objects were provided in this source excerpt, so specific table or leaf object names can't be honestly cited. Based on the RFC 4090/4327 subject matter, one would expect to poll backup-tunnel association and protection-in-use/switchover-count objects to detect a fast-reroute event, but these names aren't confirmed here.

What Can Be Monitored

  • FRR protection status
  • backup/bypass tunnel association
  • switchover events/count
  • protection availability

How to Use in IPNetwork Monitor

Example using mplsFrrFacRouteDBNumProtTunOnIf OID:

Select a device implementing MPLS-FRR-STD-MIB 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 mplsFrrFacRouteDBNumProtTunOnIf 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 protected tunnels on this interface. 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.
