Abstract:
The PCE architecture is well-defined and may be used to compute the
optimal path for LSPS across domains in MPLS-TE and GMPLS networks.
The Hierarchical Path Computation Element (H-PCE) [RFC6805] was
developed to provide an optimal path when the sequence of domains is
not known in advance. The procedure and mechanism for populating the
Traffic Engineering Database (TED) with domain topology and link
information used in H-PCE-based path computations is open to
interpretation. This informational document describes how topology
dissemination mechanisms may be used to provide TE information
between Parent and Child PCEs (within the H-PCE context). In
particular, it describes how BGP-LS might be used to provide inter-
domain connectivity. This document is not intended to define new
extensions, it demonstrates how existing procedures and mechanisms
may be used.
