Hi Anitha,
If it is a Cisco router you would definitely need CEF otherwise LFIB is not going to get built. Label swapping happens when an mpls packet arrives and there is an outgoing label for it. Label swapping is similar to ATM/FR switching.

Hi Doug,
    Thanx for the URL..It was pretty informative.
I have one query..
To run MPLS, is that CEF is necessary??
Also can anyone of you explain how exactly the label swapping occurs when a packet moves from A to B on an MPLS enabled network?
 
Thanx in advance.
 
Regards.
anitha.
