Configuring Layer 2 Bridging

This chapter describes how you can configure one or more bridge domains on MX-series routers to perform Layer 2 bridging. The Layer 2 bridging functions of the MX-series routers include integrated routing and bridging (IRB) for support for Layer 2 bridging and Layer 3 IP routing on the same interface, and virtual switches that isolate a LAN segment with its Spanning Tree Protocol (STP) instance and separate its VLAN ID space.
