I am a newbie and would really appreciate it if someone can answer the following questions.
1. How does it work if a packet is send from one network to another network and the MAC of destination if unknown? My understanding is the sender's network gateway mac address is used as the MAC destination address. But how is it send to the destination?
2. Why do we need a MAC address? Isn't IP address enough?
3. How come there are some MAC address which does not exist in the network topology?
