Hi James
Thanks for your mail
mpls ip is missed up as I changed the setup to static routing between me and the provider :)
I suspected that the setup is not working because when I checked the forwarding-table , no label was assigned for the loopback am trying to build LDP neighborship with
I have tested the scenario on gns3 with Cisco routers and it worked fine for me (with mpls ldp transport-address under the interface)
I have installed Junos image and integrated it with gns3 and lapped it up again ,
CE1 - Cisco PE - Junos PE - CE2
Please find the outputs
R1#sh mpls ldp neighbor

Now , what I have noticed is the MTU on the interfaces (and I think that is why I cannot ping between the CEs)
R1#show mpls interfaces fastEthernet 1/0 detail | inc MTU
MTU = 1500
R1#sh int f1/1 | inc MTU
MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec,
F1/0 connected to Junos and F1/1 connected to CE
root# run show interfaces em0 | match MTU

[edit]
root# run show interfaces em1 | match MTU
