L3 VPN not working

Satinderjit

I am new to MPLS and labbed up a topology to run L3VPN. I am using EIGRP as PE-CE routing protocol. 

Please see topology attached. R1 and R14 are CE routers and R2 and R13 are PE routers. 

Please ignore the back to back link between R1 and R14 as it is not configured. 

The issue is that I can see EIGRP routes exchanged between R1 and R14 but data plane is not working. The ping from R1 to R14 or vice-versa fails at PE routers.

My MPLS core is working fine as I did the this activity yesterday and it worked. After that I logged off without saving configuration.  But when I tried to do it again today it is not working. It the same configuration. Am I overlooking something?
