During discovery, IP Availability Manager queries every Cisco or Juniper device (router or switch) in the managed network for OSPF support.

IP Availability Manager queries a device’s SNMP agent for an additional MIB object named ospfIfIPAddress to determine whether the device supports the OSPF routing protocol. If ospfIfIPAddress exists for the device, IP Availability Manager adds the device to the OSPF topology collection set, along with other discovered network objects that are associated with the device.
