Layer 2 Services on MX Series Routers — Bridging, Address Learning, and Forwarding

Juniper Networks MX Series Ethernet Services Routers are Ethernet-optimized edge routers that you can configure to support Layer 2 switching and bridging functions as well as Layer 3 routing. This page contains the latest information about Layer 2 services on MX Series routers. For the latest information about MX Series router hardware, see the MX Series Ethernet Services Routers page.
