After discovering and creating the OSPF topology objects in its repository, Network Protocol Manager for OSPF monitors the status of the OSPF objects by periodically establishing SNMP sessions to the managed devices and polling the OSPF MIB objects that are listed in Instrumentation MIB objects polled by Network Protocol Manager for OSPF.

Note:

Cisco devices that support RFC 5643 are supported for IPv6 discovery and monitoring.
