Ethernet-to-EtherChannel over MPLS (Bridge) Interworking mode is also supported under VLAN.

HDLC-Ethernet over MPLS is part of Any Transport over MPLS (AToM) solution. High-Level Link 
Control (HDLC) and Ethernet are two link-layer transports that utilize the AToM architecture. This 
section describes how these two transport types can communicate with each other using the AToM 
framework. 

 shows the topology of the HDLC-Ethernet Interworking feature.

The following features are supported from Cisco IOS XE Release 3.13.0S on the Cisco ASR 1000 Series 
Aggregation Services Routers:

HDLC-Ethernet Bridged-Mode Interworking

HDLC-Ethernet Routed-Mode Interworking

HDLC Encapsulation: CISCO

Ethernet Encapsulation: Dot1Q, QinQ, Port Interface

Perform the following tasks to enable HDLC-Ethernet interworking:

Configure a controller slot on Ethernet CE:

controller E1 2/0 

channel-group 0 timeslots 1 

no shutdown 

interface Serial2/0:0 

no shutdown 

Configure an Ethernet CE interface for Ethernet interworking:

bridge irb

Specifies that the T1/E1 link uses the internal clock 
from the interface. 

 peer-loopback vc-id pw-class pe-class-name

Binds an attachment circuit to a pseudowire to 
configure an AToM static pseudowire, specifies 
MPLS as the tunneling method, and enters xconnect 
configuration mode.
