A service that
characterizes a learning bridge, in which the source Media Access Control (MAC)
address of each received packet is stored so that future packets destined for
that address can be forwarded only to the bridge interface on which that
address is located. Packets destined for unrecognized addresses are forwarded
out every bridge interface. This scheme helps minimize traffic on the attached
LANs. MAC address learning is defined in the IEEE 802.1 standard. See also
learning bridge and MAC address.
