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 issues that arise
when a P2MP-TE LSP is signaled in multi-domain networks.
Specifically, it does not provide a mechanism to avoid re-merges in
inter-domain P2MP TE LSPs.  This document provides a framework and
protocol extensions for establishing and controlling P2MP MPLS and
GMPLS TE LSPs in multi-domain networks.
 This document borrows inter-domain TE terminology from [RFC4726],
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).
