Configuring an MPLS Pseudowire with VCC Cell Relay Encapsulation
The following commands create an ATM layer 2 services over MPLS pseudowire
connection between two ATM 1483 subinterfaces on different routers. This procedure
uses the aal0 encapsulation keyword for each ATM PVC to indicate that the router
receive raw ATM cells on these circuits and forward the cells without performing
AAL5 packet reassembly. The procedure also includes optional steps for configuring
nondefault values for the ATM Martini cell packing timers and cell concatenation
parameters.
NOTE: Although this procedure uses AAL0 encapsulation to configure an MPLS
pseudowire (tunnel) connection between two ATM VCCs on different routers, you
can also use AAL0 encapsulation when you configure a local cross-connect between
two ATM 1483 subinterfaces within the same router.

(Optional) Configure values for the three ATM Martini cell packing timers on the

Create an ATM 1483 subinterface and ATM PVC with aal0 encapsulation on the
ingress interface.
host1(config)#interface atm 2/0.100
host1(config-subif)#atm pvc 100 0 100 aal0
(Optional) Configure the following cell concatenation parameters for the
ATM 1483 subinterface:
Maximum number of ATM cells that the router can concatenate in a single
packet
