Considering a loop topology between a few routers with a host connected to one of them, when it's default routing directs to the cycle.
Even when observing Wireshark, how can we know its the same packet and not different ones?
The only field that was the same was the ipV4 checksum, which seems to me a bit unintuitive as the header checksum differed. Why wouldn't they be the same?
Is there another, better way to deduce that a looped packet is indeed looped and the same packet? A thing I noticed was that the difference between all the TTL's was the cycle's length, but it's not concrete, just a guess from an observer's perspective. And if they are the same, what makes them different apart from TTLs after each cycle?
