Abstract

In one example embodiment, a method of using protocol independent multicast (PIM) in a point-to-multipoint (P2MP) label switched path is provided. In this method, a label uniquely identifying the P2MP label switched path from different P2MP label switched paths is advertised. In response to the advertisement, a PIM message is received by way of a point-to-point (P2P) label switched path. This PIM message includes the advertised label. The label included in the PIM message is identified to correspond with the P2MP label switched path and the PIM message is reflected by way of the P2MP label switched path based on the identification.
