Abstract
Disclosed is a mechanism implemented by an ingress node in a network. The mechanism comprises receiving a packet in Multiprotocol Label Switching (MPLS) format. A first segment list is pushed onto the packet. The first segment list describes a segment routing point to multipoint (SR P2MP) path as a list of multicast segment identifiers (SIDs) each comprising a multicast adjacency label. The packet is transmitted from a downstream interface along the SR P2MP path.
