Abstract
A monitoring solution allows for testing of forwarding states on network devices. In a particular example, an agent on a router A directs a probe packet to a first neighbor device. The first neighbor device reflects the probe back to the router A. The reflected probe packet undergoes a forwarding state lookup similar to other network traffic and is routed to a second neighbor network device. The second neighbor network device reflects the probe back to router A, which can then intercept the packet and redirect it to an agent on router A for verification whether the lookup was performed correctly.
