Traceroute

[lagapidis (Lazarus Agapidis)]

Hello Pradyumna

@pradyumnayadavgla

if suppose source sending ICPM echo request with TTL value which is reachable to destination in that case shall PC send first 3 icmp packet to R1 and will get 3 reply as well and so on to the next routers?

Keep in mind that ICMP echo requests and traceroute are not the same thing. An ICMP echo request (ping) only sends a single probe, and the TTL is always the maximum. Only traceroute will send multiple probes with incrementing TTLs. If the TTL on the traceroute is enough to reach the destination, it will indeed (by default) send three probes to which the destination will respond.

I hope this has been helpful!
