25.6 Introduction To Transparent Bridging

A transparent bridge is invisible to the operation of a network in that it does not modify the
frames it forwards. The bridge checks the source address of incoming frames on the port and
learns MAC addresses to associate with that port. All future communications to that MAC
address will only be sent on that port.
The bridge gradually builds a host MAC-address-to-port mapping table such as in the
following example, during the learning process.
