    abstract =  {This document specifies a mechanism to signal Point-to-Multipoint (P2MP) Pseudowires (PW) tree using LDP. Such a mechanism is suitable for any Layer 2 VPN service requiring P2MP connectivity over an IP or MPLS enabled PSN. A P2MP PW established via the proposed mechanism is root initiated.},
