RE: MPLS over GRE

If you want to run MPLS over a L3 provider, or you want to encrypt all the
traffic. Rather than running multiple IPSec sessions, one for each VRF, just
run MPLS over GRE over IPSec.

Subject: MPLS over GRE
Hi fellas,
Why it is necessary to run MPLS over GRE. Is there any design consideration
for running MPLS over GRE?.
What is the purpose of it?
My customer is running MPLS over GRE and i dont understand why they do so ?
Is there any reason behind it ?
