Displaying Routing Information With the traceroute Command

The traceroute command traces the route that an IP packet follows to a remote system. You use the traceroute command to uncover any routing misconfiguration and routing path failures. If a particular host is unreachable, you can use traceroute to see what path the packet follows to the remote host and where possible failures might be occurring.

The traceroute command also displays the round trip time for each gateway along the path to the target host. This information can be useful for analyzing where network traffic is slow between the two hosts.

For more details about the traceroute command, see the traceroute (1M) man page.
