Bridge Protocol Data Unit. BPDUs are data messages that are exchanged across the switches between LANs that are connected by a bridge. BPDU packets contain information on ports, addresses, priorities, and costs, and are exchanged across bridges to detect and eliminate loops in a network.
ARP
Address Resolution Protocol. Computers on a LAN use ARP to learn the hardware addresses (i.e. MAC addresses) of other computers when they know only their IP addresses.
IPV6 Multicast
802.1.Q
IP Multicasting under IP Protocol version 6. See IP Multicast above.
