Claim:
1. A method comprising: generating, at a network device comprising a processing device, a frame instance identifier value indicative of the network device, wherein the frame instance identifier value comprises an encoding that uniquely identifies the frame instance identifier value; embedding the frame instance identifier value at a location in a first networking frame in view of a characteristic of the first networking frame, wherein the characteristic relates to one of an Address Resolution Protocol (ARP) or a Neighbor Discovery Protocol (NSP); storing a copy of the frame instance identifier value in a mark repository; transmitting the first networking frame over a communication channel; receiving, at the network device, a plurality of networking frames that comprises the first networking frame; identifying the characteristic of the first networking frame; determining the location of the frame instance identifier value in view of the characteristic; extracting the frame instance identifier value from the location of the first networking frame; analyzing, by the processing device, the received networking frames to identify whether the first networking frame comprises the frame instance identifier value indicating that the first networking frame originated from the network device by determining whether the extracted frame instance identifier value matches the frame instance identifier value in the mark repository; and discarding the first networking frame in response to the extracted frame instance identifier value of the first networking frame matching the frame instance identifier value in the mark repository and determining that the first networking frame originated from the network device.
