Configuration Sequence
Configuring the ATM over MPLS Pseudowire Interface
You can configure ATM over MPLS is several modes according to the needs of your network. Use the
appropriate section according to the needs of your network.
Configuring N-to-1 VCC Cell Transport Pseudowire—Maps multiple VCCs to a single pseudowire
Configuring N-to-1 VPC Cell Transport—Maps multiple VPCs to a single pseudowire
Configuring ATM AAL5 SDU VCC Transport—Maps a single ATM PVC to another ATM PVC
Configuring 1-to-1 VCC Cell Mode—Maps a single VCC to a single pseudowire
Configuring a Port Mode Pseudowire—Maps one physical port to a single pseudowire connection
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
1.1.1.1 255.255.255.255 1.2.3.4.
Configuring N-to-1 VCC Cell Transport Pseudowire
An N-to-1 VCC cell transport pseudowire maps one or more ATM virtual channel connections (VCCs)
to a single pseudowire. Follow these steps to configure an N-to-1 pseudowire.
You can use the following methods to configure an N-to-1 VCC Cell Transport pseudowire.
Mapping a Single PVC to a Pseudowire
Mapping multiple PVCs to a Pseudowire
Mapping a Single PVC to a Pseudowire
To map a single PVC to an ATM over MPLS pseudowire, apply the xconnect command at the PVC
level. This configuration type only uses AAL0 encapsulation. Follow these steps to map a single
PVC to an ATM over MPLS pseudowire.
a. Configure the ATM IMA interface.
Router(config)# interface atm0/ima0
b. Use the pvc command to define a PVC.
Router(config-if)# pvc 0/40
Router(cfg-if-atm-l2trans-pvc)#
c. Use the encapsulation command to define the encapsulation type for the PVC.
Router(cfg-if-atm-l2trans-pvc)# encapsulation aal0
d. Use the xconnect command to bind an attachment circuit to the ATM IMA interface to create a
pseudowire. This example creates a pseudowire by binding PVC 40 to the remote peer 1.1.1.1.
Router(config-if)# xconnect 1.1.1.1 40 encapsulation mpls
Router(cfg-if-atm-l2trans-pvc-xconn)#
e. Use the end command to exit configuration mode.
Router(cfg-if-atm-l2trans-pvp-xconn)# end
