         Point-to-MultiPoint (P2MP) Multiprotocol Label Switching
      (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering Label
      Switched Paths (TE LSPs) may be established using signaling
      techniques described in [RFC4875]. However, [RFC4875] does not
      address many issues that comes when a P2MP-TE LSP is signaled in
      an inter-domain networks. Specifically, one of the issues in
      inter-domain networks is how to allow computation of a loosely
      routed P2MP-TE LSP such that it is re-merge free. This document
      provides a framework and required protocol extensions needed for
      establishing and controlling P2MP MPLS and GMPLS TE LSPs in
      inter-domain networks.

         This document borrows inter-domain TE terminology from [RFC
      4726], e.g., for the purposes of this document, a domain is
      considered to be any collection of network elements within a
      common sphere of address management or path computational
      responsibility. Examples of such domains include Interior Gateway
      Protocol (IGP) areas and Autonomous Systems (ASes).
