1. LDP Extensions for Multi-Topology

Publication: IETF RFC

Publication History: 2014-07

Publication URL: https://tools.ietf.org/html/rfc7307

Description:

Multi-Topology (MT) routing is supported in IP networks with the use of MT-aware IGPs. In order to provide MT routing within Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) networks, new extensions are required.

This document describes the LDP protocol extensions required to support MT routing in an MPLS environment.

2. Extensions to the Path Computation Element Communication Protocol (PCEP) for Point-to-Multipoint Traffic Engineering Label Switched Paths

Publication: IETF RFC

Publication History: 2010-09

Publication URL: https://tools.ietf.org/html/rfc6006

Description:

Point-to-point Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering Label Switched Paths (TE LSPs) may be established using signaling techniques, but their paths may first need to be determined. The Path Computation Element (PCE) has been identified as an appropriate technology for the determination of the paths of point-to-multipoint (P2MP) TE LSPs.

This document describes extensions to the PCE communication Protocol (PCEP) to handle requests and responses for the computation of paths for P2MP TE LSPs.
