Configuring ATM AAL5 SDU Support over MPLS

ATM AAL5 SDU support over MPLS encapsulates ATM AAL5 service data units (SDUs) in MPLS
packets and forwards them across the MPLS network. Each ATM AAL5 SDU is transported as one
packet.
To configure ATM AAL5 SDU support over MPLS, enter the following commands beginning in global
configuration mode:
Command
Step 1
Router(config)# interface type slot/port
Step 2
Router(config-if)# pvc [name] vpi/vci
l2transport
Step 3
Router(config-if-atm-l2trans-pvc)#
encapsulation aal5
Step 4
Router(config-if-atm-l2trans-pvc)# xconnect
peer-router-id vcid encapsulation mpls

Verifying ATM AAL5 SDU Support over MPLS

To verify that ATM AAL5 SDU support over MPLS is configured on a PVC, issue the show mpls
l2transport vc command.

shows how to enable ATM AAL5 SDU support over MPLS on an ATM PVC.
Example 20-4
Local circuit
-------------
ATM AAL5 1/100
4-port OC-3/STM-1
8-port E3/DS3
Chapter 20
Purpose
Specifies the interface by type, slot, and port number, and enters
interface configuration mode.
Creates or assigns a name to an ATM PVC.
The l2transport keyword indicates that the PVC is a switched
PVC instead of a terminated PVC. Enters L2transport VC
configuration mode.
Specifies ATM AAL5 encapsulation for the PVC.
Make sure you specify the same encapsulation type on the PE
and CE routers.
Binds the attachment circuit to a pseudowire VC.
