Study Notes
Layer 2 Physical Address (MAC Address) in Ethernet LAN
- The MAC address is used to identify devices at the data link layer (Layer 2) of the OSI model in Ethernet LAN.
MAC Address in Same-Network Communication
- When the destination IP address is on the same network, the MAC address becomes the destination MAC address.
MAC Address in Remote Network Communication
- In the context of a remote network, the MAC address for communication with the default gateway becomes the default gateway's MAC address.
Associating IPv6 Address with MAC Address
- The protocol used to associate an IPv6 address of a device with its MAC address is Neighbor Discovery Protocol (NDP).
