1. A method for testing a network device, the method comprising:
initiating, from a traffic load generator, an initial testing traffic load to a networking device, the networking device routing a portion of the initial testing traffic load to a first output port of the networking device, the first output port in communication with a load amplifier to:
replicate a payload of a first packet of the initial testing traffic load into a replicated packet, wherein a header portion of the replicated packet is identical to a header portion of the first packet;
alter the header portion of the replicated packet, the altered header portion comprising a destination address for the replicated packet different from a destination address for the first packet;
altering a source address portion of the header portion of the replicated packet to emulate a routing network device associated with the networking device under test, wherein altering the header portion of the replicated packet is based on a network routing protocol of the networking device; and
transmit the first packet and the altered replicated packet to a plurality of input ports of the networking device.
