Layer 2 Bridging, Address Learning, and Forwarding User Guide

You can configure one or more bridge domains to perform Layer 2 bridging. A bridge domain is a set of logical interfaces that share the same flooding or broadcast characteristics. Layer 2 logical interfaces are created by defining one or more logical units on a physical interface with encapsulation as ethernet-bridge or vlan-bridge. All the member ports of the bridge domain participate in Layer 2 learning and forwarding. Like a virtual LAN (VLAN), a bridge domain spans one or more ports of multiple devices. You can configure Layer 2 MAC address and VLAN learning and forwarding properties in support of Layer 2 bridging.

Use this guide to configure, monitor, and troubleshoot Layer 2 bridging, address learning, and forwarding features on your Juniper Network devices.
