Abstract
An emulation mode for network devices is described as a means of isolating a defective network device from real network traffic, while continuing to transmit faux traffic to the defective network device, wherein the faux traffic is intentionally dropped. The emulation mode allows the defective network device to be tested in an environment that appears real, without impacting user traffic. A management server can control one or more neighbor network devices and place them in the emulation mode as a way to isolate and test the defective network device. In the emulation mode, the neighbor network device monitors for packets that, based on previous routing history, would be sent to the defective network device and, instead, routes them to functioning network devices using a current FIB. A virtual RIB/FIB can also be used to route the same packets to the defective network device.
