MIBs
accessed for OSPF discovery
sends SNMP requests to Cisco and Juniper devices to discover
routing topology objects and their relationships. It supports SNMPv1,
v2c, and v3 access to the OSPF MIB objects that are defined in RFC
1253.
reads the OSPF MIB objects that are identified in this section
to discover the following routing topology objects and their relationships:
- OSPF areas
- OSPF area configurations
- OSPF services
- OSPF networks
- OSPF interfaces
- OSPF virtual interfaces
- OSPF neighbor endpoints
- OSPF virtual neighbor endpoints
- OSPF neighbor relationships
- OSPF virtual linksAfter discovering and creating the OSPF topology objects in its repository, monitors the status of the OSPF objects by periodically establishing SNMP sessions to the managed devices and polling the OSPF MIB objects that are identified in the.MIB objects accessed for OSPF discovery lists the discovery OSPF MIB objects that are accessed by .
MIB object | OID | Description | Module |
|---|---|---|---|
ospfRouterId | .1.3.6.1.2.1.14.1.1 | A
32-bit integer that uniquely identifies the device in the autonomous
system (AS). Typically defaults to one of the device’s IP interface
addresses. | OSPF MIB |

this device is configured as an AS Border Router (ASBR). | OSPF MIB |
ospfAreaId | .1.3.6.1.2.1.14.2.1.1 | A 32-bit integer that uniquely identifies an OSPF
area. Area ID 0.0.0.0 is used for the OSPF backbone. | OSPF
MIB |
ospfImportAsExtern | .1.3.6.1.2.1.14.2.1.3 | OSPF area’s support for importing AS external link-state
advertisements (LSAs). | OSPF MIB |

ospfIfAreaId | .1.3.6.1.2.1.14.7.1.3 | A 32-bit integer that uniquely identifies the OSPF
area to which the OSPF interface connects. Area ID 0.0.0.0 is used
for the OSPF backbone. | OSPF MIB |
ospfIfType | .1.3.6.1.2.1.14.7.1.4 | OSPF
interface type. For example, broadcast LANs such as Ethernet take
the value broadcast . | OSPF MIB |
ospfIfAdminStat | .1.3.6.1.2.1.14.7.1.5 | OSPF interface’s administrative status. | OSPF MIB |
ospfIfTransitDelay | .1.3.6.1.2.1.14.7.1.7 | Estimated number of seconds
to transmit a link-state update packet over this OSPF interface. | OSPF MIB |
ospfIfRetransInterval | .1.3.6.1.2.1.14.7.1.8 | Number of seconds
between LSA retransmissions, for adjacencies that belong to this OSPF
interface. | OSPF MIB |
ospfIfPollInterval | .1.3.6.1.2.1.14.7.1.11 | Interval, in seconds,
between the Hello packets sent to an inactive non-broadcast multi-access
neighbor. | OSPF MIB |
ospfIfMulticastForwarding | .1.3.6.1.2.1.14.7.1.18 | Specifies how
multicasts are forwarded on this OSPF interface: Not forwarded, forwarded
as data-link multicasts, or forwarded as data-link unicasts. | OSPF MIB |
ospfIfDemand | .1.3.6.1.2.1.14.7.1.19 | Indicates whether Demand OSPF procedures (for example,
Hello suppression to full neighbors) should be performed on this interface. | OSPF MIB |
ospfVirtIfTransitDelay | .1.3.6.1.2.1.14.9.1.3 | Estimated number
of seconds to transmit a link-state update packet over this OSPF virtual
interface. | OSPF MIB |
ospfVirtIfRetransInterval | .1.3.6.1.2.1.14.9.1.4 | Number of seconds
between LSA retransmissions, for adjacencies that belong to this OSPF
virtual interface. | OSPF MIB |
ospfVirtNbrArea | .1.3.6.1.2.1.14.11.1.1 | Transit area identifier. | OSPF MIB |
ospfVirtNbrRtrId | .1.3.6.1.2.1.14.11.1.2 | A 32-bit integer that uniquely identifies the neighboring device
in the AS. | OSPF MIB |
ospfVirtNbrIpAddr | .1.3.6.1.2.1.14.11.1.3 | IP address that
this virtual neighbor is using. | OSPF MIB |
ospfNbrRtrId | .1.3.6.1.2.1.14.10.1.3 | A 32-bit integer that uniquely identifies the neighboring device
in the AS. | OSPF MIB |
ospfNbmaNbrStatus | .1.3.6.1.2.1.14.10.1.9 | Displays the status
of the entry. Setting it to invalid has the effect of making it inoperative. | OSPF MIB |
ospfNbmaNbrPermanence | .1.3.6.1.2.1.14.10.1.10 | Displays the status
of the entry; dynamic and permanent refer
to how the neighbor became known. | OSPF MIB |
ospfNbrHelloSuppressed | .1.3.6.1.2.1.14.10.1.11 | Indicates whether Hellos are being suppressed to the
neighbor. | OSPF MIB |
ospfVirtNbrHelloSuppressed | .1.3.6.1.2.1.14.11.1.8 | Indicates whether
Hellos are being suppressed to the virtual neighbor. | OSPF
