Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Router(config-if-cem)# signaling inband-cas
Step 6 Use the xconnect command to bind an attachment circuit to the CEM interface to create a pseudowire.
This example creates a pseudowire by binding the CEM circuit 305 to the remote peer 30.30.30.2.
Router(config-if-cem)# xconnect 30.30.30.2 305 encapsulation mpls
Note When creating IP routes with a pseudowire configuration, we recommend that you build a route from
the xconnect address (LDP router-id or loopback address) to the next hop IP address , such as
ip route
30.30.30.2 255.255.255.255 1.2.3.4.
Step 7 Use the exit command to exit the CEM interface.
Router(config-if-cem)# exit
Router(config)#
Configuring Transportation of Service Using ATM over MPLS
ATM over MPLS pseudowires allow you to encapsulate and transport ATM traffic across an MPLS
network. This service allows you to deliver ATM services over an existing MPLS network.
The following sections describe how to configure transportation of service using ATM over MPLS:
• Configuring the Controller
• Configuring an IMA Interface
• Configuring the ATM over MPLS Pseudowire Interface
• Optional Configurations
Note For sample configurations for ATM over MPLS, see the “ATM over MPLS Configuration” section on
page A-17.
Configuring the Controller
Follow these steps to configure the controller.
Step 1 Enter the card type command to configure IMA on an E1 or T1 interface.
Router(config)# card type e1 0 0
Step 2 Specify the controller interface on which you want to enable IMA.
Router(config)# controller E1 0/4
Router(config-controller)#
Step 3 Set the clock source to internal.
Router(config-controller)# clock source internal
Step 4 If you want to configure an ATM IMA backhaul, use the ima-group command to assign the interface to
an IMA group. For a T1 connection, use the no-scrambling-payload to disable ATM-IMA cell payload
scrambling; for an E1 connection, use the scrambling-payload parameter to enable ATM-IMA cell
payload scrambling.
