PC1 - SW - PC2, PC3
When PC1 ping PC2's private IP address, PC1 would send the ARP first. SW would definitely flood the ARP packet. My question is that which one is more accurate way to say this phenomenon? My answer is definitely "Unknown Unicast Flooding'. But my friend is insisting that he has never heard of the world "Unknown Unicast Flooding'. He said answer is just "flooding'. Which one is the more accurate terminology to describe this phenomenon?
