Hi Nitin,
Here the info :

Can you share the exact command that you are using?
           mpls ldp ip-forwarding
Have you tried using 'mpls ldp ip-forwarding host-only'?
          Yes, but the problem continues.
Did you do a 'clear mpls ldp' after entering the above command?
          Yes, clear mpls ldp and clear ip bgp *
Do the routes in the IP routing table point to the MPLS major interface
(ip***.mpls)?
          I don´t undernstand this question, I configured MPLS on the
interface GigabitEthernet0/0.500 .
          Here some info from the ERX :
