You might also sometimes see the tracert command referred to as the trace route command or traceroute command. It is designed to help troubleshoot and check the overall health of your cisco supported software. In the following example, the default gateway has found that there is no valid path for the host on 22. Probably, either the router has a configuration problem, or the 22.
