The OSPF default polling group is used by Network Protocol Manager for OSPF to monitor the availability of OSPF sessions (OSPF neighbor relationships, OSPF virtual links). Network Protocol Manager for OSPF monitors the availability by monitoring the OSPFInterfaces and OSPFVirtualInterfaces that are discovered on Cisco or Juniper devices.

Note:

Because the standards-based OSPF MIB (defined in RFC 1253) is used by both Cisco and Juniper devices, Network Protocol Manager for OSPF uses SNMP to discover and monitor OSPF topology for Cisco and Juniper devices. The OSPF polling group uses SNMP polling to monitor the OSPF sessions by monitoring the OSPFInterfaces and OSPFVirtualInterfaces on the discovered devices.

The OSPF polling group has a default setting and an optional setting:

  • OSPF SNMP Setting (default)

  • OSPF External Setting (optional)

    The two settings are mutually exclusive, which means that only one or the other (but not both) can be specified for an OSPF polling group at any given time.
