Step 1

They operate at the data link layer (Layer 2) of the OSI model, which means they use MAC addresses for forwarding frames, not IP addresses. (ii) As mentioned earlier, bridges use data link layer addresses (MAC addresses) to do routing. This statement is Show more…

Key Concepts

Protocol Agnosticism in LANs

Local Area Networks (LANs) are designed to support a variety of protocols—such as IPv4, IPv6, AppleTalk, ATM, and OSI—because the data forwarding process at the Data Link Layer does not depend on the specific network layer protocol. Bridges facilitate this protocol independence by operating solely on MAC addresses.

Data Link Layer Addressing

Data Link Layer addressing involves the use of MAC addresses, which are unique identifiers assigned to network interfaces. Bridges use these addresses to effectively forward frames between network segments, rather than making decisions based on network layer addresses like IP addresses.

Bridge

A bridge is a networking device that operates at the Data Link Layer (Layer 2) of the OSI model. It connects multiple network segments, forwarding frames based on MAC addresses without filtering traffic based on higher-level protocol information.
