Several useful applications of MPLS tunnels based on LSPs with second level labels between non adjacent LSRs have been identified: IP-VPNs and VoIP over MPLS are just two examples. This tunnelling technique can easily be extended to non-MPLS core networks. This Internet-Draft explains the motivation for encapsulating MPLS messages in IP and provides the protocol specification of the encapsulation.
