31.6 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.

HOST MAC ADDRESS PORT

00a0c5123456

00a0c5123478 (host A) 1

00a0c512349a
