User Guidelines
The traceroute command works by taking advantage of the error messages
generated by routers when a datagram exceeds its time-to-live (TTL) value.
The traceroute command starts by sending probe datagrams with a TTL
value of one. This causes the first router to discard the probe datagram and
send back an error message. The traceroute command sends several probes at
each TTL level and displays the round-trip time for each.
