Abstract: A network node may receive a packet that originated from a root network node and may process the packet to determine segment identifier (SID) information associated with a point-to-multipoint transport chain. The network node may determine, based on the SID information, that the network node is a transit leaf node in the point-to-multipoint transport chain. The network node may generate, based on determining that the network node is a transit leaf node in the point-to-multipoint transport chain, a copy of the packet and may process the copy of the packet to perform one or more actions. The network node may update, based on determining that the network node is a transit leaf node in the point-to-multipoint transport chain, the SID information and may send, after updating the SID information, the packet, with the updated SID information, to another network node.
