Service providers continue to deploy real-time multicast applications using Multicast LDP (mLDP) across MPLS networks. There is a clear need to protect these real-time applications and to minimize switching times in the event of failure. This document outlines the requirements, procedures and extensions to facilitate mLDP Point-to-Multipoint (P2MP) and Multipoint-to- Multipoint (MP-to-MP) LSP protection within an MPLS network.
