The Traceroute tool is similar to the ping tool except that it shows the results of a ping to each router on route to its destination. Some of the advanced options of the ping tool are also offered here. The TTL (Time to Live) should be set with care. The value will determine how many hops will be evaluated. The output of the traceroute is also similar to the ping in terms of the information shown. But unlike the ping where each output shows the success at reaching the destination, the traceroute tool shows the success at reaching the router at each step along the path to the destination. The Average, Max and Min RTT (Round Trip Time) is shown, as well the number of pockets sent, received and percent received at each stage. For a more detailed explanation of the advanced parameters see the ping tools documentation above.
A traceroute is said to have succeeded if the destination was reached. Just like the ping tool, failure to reach the destination does not always imply a failure. Firewalls may block ping responses after a point in the route. Administrators may also, for some reason, setup devices so they do not respond to ping requests.
