Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is BAS-OSPF-MIB?
BAS-OSPF-MIB manages OSPF (Open Shortest Path First) routing protocol configuration and link-state database information on Broadband Access System IP forwarding platforms. Its data spans routing configuration (the general OSPF group table) and route/statistics groupings broken out by route class -- intra-area, inter-area, and external type-1/type-2 routes. From a monitoring perspective it is used to track the health and stability of a device's OSPF routing process, since counts and states in basOspfIntraArea, basOspfInterArea, basOspfExternalType1, and basOspfExternalType2 reveal whether route counts in each category are stable or fluctuating, with route churn often signaling adjacency flaps or an unstable upstream neighbor. As a vendor extension to standard OSPF management, it is closely tied to the IETF OSPF-MIB (RFC 1850/4750) conventions for terminology and route classification even though it is a BAS-specific implementation. It is deployed on Broadband Access System routers/edge platforms used by broadband/cable operators for IP aggregation and routing. Engineers can download the BAS-OSPF-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in BAS-OSPF-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
- Broadband Access System (BAS) routers and IP aggregation platforms
Monitoring Examples
An operator would poll basOspfGeneralGroupTable/basOspfGeneralGroupEntry for overall OSPF process configuration and status, then check the basOspfRouteGroup counters split across basOspfIntraArea, basOspfInterArea, basOspfExternalType1, and basOspfExternalType2 to see how many routes of each class are currently installed. A sudden drop in basOspfIntraArea route counts would suggest an area adjacency has gone down, while spikes in basOspfExternalType2 could indicate route redistribution instability from an external protocol. This data would typically be trended over time to catch OSPF flapping before it causes a routing outage.
What Can Be Monitored
- OSPF general process status
- intra-area route count
- inter-area route count
- external type-1 route count
- external type-2 route count

This sum can be used to determine if there has been a change in a router's link state database, and to compare the link-state database of two routers. |
| T/F basOspfTOSSupport | 1.3.6.1.4.1.3493.2.7.7.1.1.1.8 | TruthValue | read-write | The router's support for type-of-service rout- ing. |

If the value is -1, then there is no limit. When the number of non-default AS-external-LSAs in a router's link-state database reaches ospfExtLsdbLimit, the router enters Overflow- State. The router never holds more than ospfExtLsdbLimit non-default AS-external-LSAs in its database. OspfExtLsdbLimit MUST be set identically in all routers attached to the OSPF backbone and/or any regular OSPF area. (i.e., OSPF stub areas and NSSAs are excluded). |

Bit 0, if set, indicates that the router can forward IP multicast datagrams in the router's directly attached areas (called intra-area mul- ticast routing). Bit 1, if set, indicates that the router can forward IP multicast datagrams between OSPF areas (called inter-area multicast routing). Bit 2, if set, indicates that the router can forward IP multicast datagrams between Auto- nomous Systems (called inter-AS multicast rout- ing). Only certain combinations of bit settings are allowed, namely: 0 (no multicast forwarding is enabled), 1 (intra-area multicasting only), 3 (intra-area and inter-area multicasting), 5 (intra-area and inter-AS multicasting) and 7 (multicasting everywhere). By default, no mul- ticast forwarding is enabled. |

It has no effect on other areas. If it is noAreaSummary, the router will neither originate nor propagate summary LSAs into the stub area. It will rely entirely on its de- fault route.
