Transparent bridges are devices which connects more than one network segments with other bridges
to make all routing
decisions. A transparent bridge is essentially used to learn the MAC addresses
of all nodes
and their associated port
, to filter
incoming frames whose destination MAC addresses are located on the same incoming port, and to forward incoming frames to the destination MAC through their associated [email protected]
There are two types of Transparent Bridge Modes:
- Store-and-Forward: Stores the entire frame and verifies the CRC before forwarding the frame. If a CRC error is detected, the frame is discarded.
- Cut-Through: Forwards the frame just after it reads the destination MAC address without performing a CRC check.
