This project adds Open Shortest Path First (OSPF) Protocol as asouthboundpluga southboundplug-in in inin ONOS controller to collect the topology information of the network. This network topology can be used by other applications like PCE.
...
Open Shortest Path First (OSPF) is an interior gateway protocol (IGP) for routing Internet Protocol (IP) packets solely within a single routing domain, such as an autonomous system. It gathers link state gatherslinkstate information from available routers and constructs a topology map of the network.

- Other opaque information with OSPF as a mechanism to flood it
It should be noted that OSPFon OSPF on ONOS(SDN controller) doesn’t need to be a full OSPF implementation as needed by a router (as per RFC 2328).

Following documents outline the procedure to run OSPF as SBI and connect with the routers that support OSPF.
