The ability to compute constrained Traffic Engineering Label
Switched Paths (TE LSPs) for point-to-multipoint (P2MP) LSPs
in Multiprotocol Label Switching (MPLS) and Generalized MPLS
(GMPLS) networks across multiple domains (where a domain is
a collection of network elements within a common sphere of
address management or path computational responsibility such
as an IGP area or an Autonomous Systems) has been identified
as a key requirement [PCEP-P2MP-REQ]. This document addresses
this requirement by extending backward recursive path
computation (BRPC) technique proposed for Point-to-Point
(P2P) LSPs in [P2P-BRPC] for P2MP LSP path computation in a
multiple domains network.
