Bridging 1-13
Figure 1-11, Figure 1-12, Figure 1-13 and Figure 1-14 illustrate
how a bridge learns device addresses and uses address lists to
reduce unnecessary network traffic.
Figure 1-11
: The bridge does not know what devices are on the
network.

An Example Network
Figure 1-12: Device A, connected to port 1, transmits a packet for
device B. The bridge learns the address of device A but does not
know where device B is, so it passes the packet to ports 2, 3 and
E.
