I setup a service provider lab in unetlab using vmx version 14.1R1.10 .
The IGP for running the RSVP and MPLS between P and PE routers is using OSPF.
PE and PE is using Ibgp.
Also there is tunnel configured between PE and PE.
This seems like simple setup.
But the PE can only ping the CE that is connected to it not the remote CE.
One CE is connected to PE using static and another is using EBGP.
Hope you guys can share some inputs.
VMX2 show cmd output.

Attached is the config of each VMX and show logs as well.
"Unverified" does not indicate an invalid path, but warns that this path has not been validated by Origin validation configuration.Origin validation helps to prevent the unintentional advertisement of routes.
Please refer the below Juniper KB on Unverified validation state.
KB27919 [Junos Platform] What does "validation-state: unverified" mean in show route command during BGP configuration?
