Can you please answer me a simple question?
Imagine a host A, host B with an IP addresses A and B. Host B is not sending any packets (except replying to ping/ARP). There is one switch as well they are both connected to.Host A pings host B.
Switch has no MAC addresses recorder yet. What will happen - switch will send ARP broadcast for host B, it will reply, switch will record it and forward traffic here. Simple. But now, what will happen if the host B will change MAC address after that initial successful ping?
Will host A get ping timeout response? Or will host A manage to ping the host B? Is a mac-address clearing needed? Etc..
Please share your thoughts!
