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 links
    After 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 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

.1.3.6.1.2.1.14.1.2
Administrative status of OSPF in the device.
OSPF MIB

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

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
.

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.
