• source ip-address —One of the interface addresses of the device to use as a
source address for the probes. The device selects the optimal source
address by default. (Range: Valid IP address)

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.
The traceroute command sends out one probe at a time. Each outgoing
packet can result in one or two error messages. A "time exceeded” error
message indicates that an intermediate router has seen and discarded the
probe. A "destination unreachable" error message indicates that the
destination node has received the probe and discarded it because it could not
deliver the packet. If the timer goes off before a response comes in, the
traceroute command prints an asterisk (*).
The traceroute command terminates when the destination responds, when
the maximum TTL is exceeded, or when the user interrupts the trace with
Esc.
The traceroute command is not relevant to IPv6 link local addresses.
