Abstract:
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. Another issue
is reoptimization of a P2MP-TE tree vs. reoptimization of
an individual destination, 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).
