An apparatus and method is disclosed for segment routing (SR) over label distribution protocol (LDP). In one embodiment, the method includes a node receiving a packet with an attached segment ID. In response, the node may attach a label to the packet. Thereafter, the node may forward the packet with the attached label and segment ID to another node via a label switched path (LSP).
