MAC Address Learning
MAC Address Learning characterizes a learning
bridge, in which the packet’s source MAC address is
recorded. Packets destined for that address are
forwarded only to the bridge interface on which that
address is located. Packets addressed to unknown
addresses are forwarded to every bridge interface.
MAC Address Learning minimizes traffic on the
attached LANs.
