Existing techniques provide a Point-to-point (P2P) Label Switch Path (LSP) protection mechanism for mLDP nodes. In situations where the data duplication along the p2p backup path is not acceptable, a Point-To-Multipoint (P2MP) or Multipoint-To-Multipoint (MP2MP) LSPs is needed, instead of a P2P LSPS, for the protection of mLDP nodes. This document defines procedures and protocol extensions for protection of mLDP nodes within Multi-Protocol Label Switching (MPLS) networks using P2MP and MP2MP backup LSPs.
