Title : Signaling RSVP-TE P2MP LSPs in an Inter-domain Environment

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 come when a P2MP-TE LSP is signaled in
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. Another issue is
reoptimization of a P2MP-TE tree vs. reoptimization of an
individual destination sub-LSP, as loosely routing domain border
node is not aware of the reoptimization scope. This document
provides a framework and required protocol extensions needed for
establishing, controlling and reoptimizing 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).
