def configOspfv3(self, obj=None, routerId=None, port=None, portName=None, ngpfEndpointName=None, hostIp=None, **kwargs):
        """
        Description
            Create or modify OSPFv3. If creating a new OSPFv3, provide an IPv6 object handle.
            If modifying a OSPF, there are five options. 2-6 will query for the OSPFv3 object handle.

               1> Provide the OSPFv3 object handle using the obj parameter.
               2> Set routerId.
               3> Set port: The physical port.
               4> Set portName: The vport port name.
               5> Set NGPF OSPF name that you configured.
               6> Set hostIp: The src IP.

        Parameters
            IPv6 object handle example:
               obj: /api/v1/sessions/1/ixnetwork/topology/1/deviceGroup/1/ethernet/1/ipv6/1

            OSPF object handle example:
               obj: /api/v1/sessions/1/ixnetwork/topology/1/deviceGroup/1/ethernet/1/ipv6/1/ospfv3/1

            routerId: <str>: The router ID IP address.
            port: <list>: Format: [ixChassisIp, str(cardNumber), str(portNumber)]
            portName: <str>: The virtual port name.
            ngpfEndpointName: <str>: The name that you configured for the NGPF endpoint.
            hostIp: <src>: The source IP address to query for the object.
            kwargs: OSPF configuration attributes. The attributes could be obtained from the IxNetwork API browser.

        Syntax
            POST:  /api/v1/sessions/{id}/ixnetwork/topology/{id}/deviceGroup/{id}/ethernet/{id}/ipv6/{id}/ospfv3
            PATCH: /api/v1/sessions/{id}/ixnetwork/topology/{id}/deviceGroup/{id}/ethernet/{id}/ipv6/{id}/ospfv3/{id}

        Example:
            ospfObj1 = configOspf(ipv6Obj,
                          name = 'ospf_1',
                          areaId = '0',
