What Is PRVT-OSPF-EXTENSION-MIB?
PRVT-OSPF-EXTENSION-MIB is a BATM Advanced Communication proprietary MIB module that extends standard OSPF (Open Shortest Path First) protocol management for BATM's carrier/enterprise networking equipment. It defines supplemental OSPF configuration objects covering additional area parameters and metric manipulation controls that go beyond what the standard OSPF-MIB provides. Because it is purely an OSPF protocol-extension module, its relevance to hardware/software status monitoring is indirect: it lets an operator verify that vendor-specific OSPF area and cost/metric settings are configured as intended, a software/routing-configuration check rather than a hardware health check, though a misconfigured metric here can manifest as routing instability worth correlating with interface and CPU status elsewhere on the platform. It is explicitly built as an extension to the standard IETF OSPF-MIB, depending on and supplementing that standard's area and interface conventions rather than replacing them. Administrators who download PRVT-OSPF-EXTENSION-MIB definitions typically deploy them on BATM Advanced Communication routers/switches running OSPF in carrier or enterprise networks that need finer-grained area and metric control than the base OSPF-MIB offers.
IPNetwork Monitor allows you to monitor SNMP objects defined in PRVT-OSPF-EXTENSION-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.
What Can Be Monitored
- OSPF area configuration (vendor extensions)
- OSPF metric/cost manipulation settings
- custom OSPF routing behavior vs. RFC baseline
Supported Devices
- BATM Advanced Communication OSPF-capable routers/switches
Monitoring Examples
No sample objects were provided for this module, so specific object or table names cannot be cited. Consistent with its stated purpose of supplementing standard OSPF protocol control, a real deployment would poll the extended area-configuration and metric-manipulation objects to confirm a custom OSPF area or route-cost override matches the intended routing design. An operator noticing unexpected path selection or an area boundary behaving differently than expected might check these extension objects alongside the standard OSPF-MIB tables (ospfAreaTable, ospfIfMetricTable) to isolate whether a BATM-specific override is the cause. Without concrete object names, this scenario is grounded only in the module's stated OSPF-extension purpose.

| T/F ospfEnable | 1.3.6.1.4.1.738.1.6.4.2.1.1 | TruthValue | read-write | This object enables/disables the OSPF process in the switch |
| ospfRedistributeTable | 1.3.6.1.4.1.738.1.6.4.2.1.2 | not-accessible | The table represents the routing protocols, redistributed into the OSPF routing domain. Creation of conceptual row in the table starts the redistribution of the specified protocol, which would lead to the injection of routing information from that protocol into the OSPF. Deletion of conceptual row would stop the redistribution of that protocol into the OSPF. OSPF router, which redistributes routing information from other protocols, is an ASBR router | |

| INT ospfRedistributeProtocol | 1.3.6.1.4.1.738.1.6.4.2.1.2.1.1 | INTEGER | read-create | The specific routes redistributed into OSPF. For T4R model the valid values are connected, rip and static. For all the other models all of the above routes can be redistributed |
| INT ospfRedistributeMetric | 1.3.6.1.4.1.738.1.6.4.2.1.2.1.2 | INTEGER | read-create | The metric, with which the external routes will be redistributed in the OSPF |
| INT ospfRedistributeMetricType | 1.3.6.1.4.1.738.1.6.4.2.1.2.1.3 | INTEGER | read-create | The type of metric, with which the external routes are advertised into the OSPF routing domain. OSPF supports two types of external metrics. Type 1 external metrics are expressed in the same units as the OSPF interface cost (i.e., in terms of the link state metric). Type 2 external metrics are an order of magnitude larger; any Type 2 metric is considered greater than the cost of any path internal to the AS. Use of Type 2 external metrics assumes that routing between AS'es is the major cost of routing a packet, and eliminates the need for conversion of external costs to internal link state metrics. |
| OCT ospfRedistributeRouteMap | 1.3.6.1.4.1.738.1.6.4.2.1.2.1.4 | OCTET STRING | read-create | The route map that would filter the redistributed routing information |
| ROW ospfRedistributeRowStatus | 1.3.6.1.4.1.738.1.6.4.2.1.2.1.5 | RowStatus | read-create | Indicates the status of the row. Setting of this field to active enables the redistribution of the protocol. Setting this field to destroy disables the redistribution of the protocol. |
FAQ
What does PRVT-OSPF-EXTENSION-MIB add for a BATM Advanced Communication device beyond the standard OSPF MIB?
It carries additional information needed to control the OSPF protocol that isn't found in the standard RFC-based OSPF MIB, including extensions for additional area configuration and metric manipulation.
When would a network engineer need to look at PRVT-OSPF-EXTENSION-MIB instead of just the standard OSPF MIB?
When they need to configure or verify OSPF area settings or route metrics beyond what the standard RFC OSPF MIB objects expose -- this vendor extension module is specifically for that additional area and metric control on BATM routing equipment.
