I tried to implement cell-mode MPLS by connecting 3 routers with ATM interfaces. The traceroute shows label switching rather than VPI/VCI switching (atleast I was expecting to see that).
R0---R3---R2
R0 router:
interface Loop 0
ip add 1.1.1.1 255.255.255.255
ip ospf 1 area 0
!
int atm 1/0
no ip add
!
int atm 1/0.10 mpls
ip unnumbered Loop 0
mpls ip
ip ospf 1 area 0
!
R3 router:
interface Loop 0
ip add 2.2.2.2 255.255.255.255
ip ospf 1 area 0
!
int atm 1/0
no ip add
!
int atm 1/0.10 mpls
ip unnumbered Loop 0
mpls ip
ip ospf 1 area 0
!
int atm 2/0
no ip add
!
int atm 2/0.20 mpls
ip unnumbered Loop 0
mpls ip
ip ospf 1 area 0
R2 router:
interface Loop 0
ip add 3.3.3.3 255.255.255.255
ip ospf 1 area 0
!
int atm 1/0
no ip add
!
int atm 1/0.20 mpls
ip unnumbered Loop 0
mpls ip
ip ospf 1 area 0
!

Amit,
According to the following documents you are missing a few commands:
interface ATM1/0.10 mpls
ip unnumbered Loopback0
mpls atm control-vc 10 32
mpls atm vpi 10 vci-range 33-65535
mpls ip
end

Thank you for your reply but I think you can leave the control VC to 0/32 (by default,which is used for control).Also, VPI/VCI range can also be left to default.
