Overview

Bridged Ethernet allows multiple upper-layer interface types (IP and PPPoE) to be simultaneously multiplexed over the same interface. You can set up the router to either terminate interfaces and route data or to pass data transparently through the router to another terminating device. This capability supports multiple client devices that use both IP and Point-to-Point Protocol over Ethernet (PPPoE) encapsulation over an Ethernet LAN.

Note: Although connection-based forwarding is not supported on any E-series router, as an alternative, you can configure a local cross-connect, which uses layer 2 services over MPLS to transmit data between two layer 2 interfaces that reside on the same E-series router. Configuration of local cross-connects is supported on all E-series routers. For more information about configuring local cross-connects, see chapter Configuring Layer 2 Services over MPLS in JUNOSe BGP and MPLS Configuration Guide.
