Principles of the invention relate to techniques for transmission of Layer 2 (L2) traffic over a point to multi-point (P2MP) label switched path (LSP) within a multi-protocol Label Switching (MPLS) network. A source or ingress network device may implement the techniques to connect multiple L2 interfaces to a P2MP LSP within an MPLS network via a P2MP Pseudo-Wire (PW) mechanism that emulates delivery of L2 data units over a packet switched network, such as the MPLS network. The ingress network device first establishes the P2MP LSP and then connects two or more L2 interfaces to the P2MP LSP via the P2MP PW mechanism. Egress network devices may also implement the techniques to terminate the P2MP LSP and de-multiplex traffic arriving via multiple P2MP PWs carried over the same P2MP LSP.
