The number of OSPF packets received that have been dropped, for a reason which does not have a more specific type defined in the DC-OSPF user exit interface. This count is incremented when a received OSPF packet is dropped for a reason that is not defined in the DC-OSPF user exit interface. When this count is incremented, another count in this row will also be incremented depending on the reason why the packet was dropped. The count in this field should not be included when determining the total number of OSPF packets that have been dropped. The count is reinitialized to zero when interface statistics collection is reset.
