I have a scenario as depicted below.
Here two host machines are connected via a hub:
Ok, so host-1 wants to ping host-2 and i have setup wireshark on a 3rd host connected to the same hub. Now surprisingly for a single ping command to work, i see 6 packets, while there should be 4. Here it is what i see from wireshark:
Now what is beyond my understanding is that why the packet 5 & 6 are generated while isn't on ARP reply destination already knows the sender mac already.
Or is there something wrong with my understanding, please help.
