Abstract
A method, apparatus and computer program product for building multipoint Pseudo Wires (PWs) using Multicast Label Distribution Protocol (MLDP) is presented. A multipoint PW leaf identifier (mTAI) is configured on one or more Layer 2 (L2) leaf interface(s) of a multipoint PW. A multipoint PW root identifier identifying the root of the multipoint PW is also configured and an opaque value is computed, the opaque value used in MLDP label mapping messages that will flow upstream towards a the root of the multipoint PW. The opaque value is computed from the multipoint leaf identifier and the multipoint root identifier. The PE leaf routers direct MLDP label mapping to the root PE router via a core network.
