Just want to clarify that OFP project only provides operational topology: /restconf/operational/network-topology:network-topology/topology/flow:1 that BTW cannot be modified by user because this is discovered using LLDP packets as described in the docs. I am not sure what is the purpose of reading/writting in the config topology: /restconf/configuration/network-topology:network-topology/topology/flow:1, but whatever it is, it is not implemented in ODL.
