an MPLS relay connection from the PVCs to the loopback interface. You do not need
to configure any other MPLS commands.
The following commands create an ATM cross-connect between two ATM
subinterfaces on the same router.
NOTE: Although this procedure uses AAL5 encapsulation to configure a local
cross-connect between two ATM 1483 subinterfaces within the same router, you can
also use AAL5 encapsulation when you configure an MPLS pseudowire (tunnel)
connection between two ATM VCCs on different routers.
Create a loopback interface. All local cross-connects can share the same loopback

interface.
host1(config)#interface loopback 0
host1(config-if)#ip address 10.1.1.1 255.255.255.255
host1(config)#exit
Create an ATM 1483 subinterface and ATM PVC with aal5all encapsulation on
2.
the ingress interface.
host1(config)#interface atm 2/0.1
host1(config-subif)#atm pvc 1 0 100 aal5all
Create an MPLS relay connection to the loopback interface. Include the address
3.
of the loopback interface and a VC ID.
host1(config-subif)#mpls-relay 10.1.1.1 2
host1(config-subif)#exit
Create an ATM 1483 subinterface and ATM PVC with aal5all encapsulation on
4.
the egress interface.
host1(config)#interface atm 2/0.2
host1(config-subif)#atm pvc 2 0 101 aal5all
Create an MPLS relay connection to the loopback interface. The VC ID must be
5.
the same on both sides of the connection.
host1(config-subif)#mpls-relay 10.1.1.1 2
host1(config-subif)#exit
