Are you able to ping 172.16.0.1 from your router (which is connected to MPLS Network). If not then you have to tell your MPLS router where is 172.16.0.0 connected. Do you have access on this router? If you copy paste config here that would be helpful. I suspect that your ping request is reaching MPLS router but router does not have a route for this network. If this router is on the other side of MPLS network then it is possible that ping is blocked by your service provider to hide intermediate nodes. I don't think that you need any tunneling protocol for this as it is already taken care by your provider.
