4.13.5 Trace Router
Traceroute function is for testing the gateways through which the data packets travel from the source device to the destination
device, so to check the network accessibility and locate the network failure.
Execution procedure of the Traceroute function consists of: first a data packet with TTL at 1 is sent to the destination address, if
the first hop returns an ICMP error message to inform this packet can not be sent (due to TTL timeout), a data packet with TTL
at 2 will be sent. Also the send hop may be a TTL timeout return, but the procedure will carries on till the data packet is sent to its
destination. These procedures is for recording every source address which returned ICMP TTL timeout message, so to describe
a path the IP data packets traveled to reach the destination. The Trace Route Setting screen in Figure 4-13-5 appears.
