Bridge

Bridge
Overview

A bridge is a networking device that connects and filters traffic between two network segments. It operates at Layer 2 (Data Link Layer) of the OSI model.

Key Functions
  • Connects separate network segments
  • Filters traffic between network segments based on MAC addresses
  • Reduces network traffic by segmenting networks
  • Improves network performance by isolating collision domains
OSI Model Layer

Bridges operate at Layer 2 (Data Link Layer) of the OSI model. They use MAC addresses to make forwarding decisions and can filter traffic between network segments.
