1. A method comprising:
- a node receiving an instruction to create a tunnel between the node and another node via a plurality of nodes in data communication between the node and the other node;
in response to receiving the instruction, the node creating a stack of segment identifiers each of which corresponds to a respective one of the plurality of nodes;
the node mapping a first identifier (ID) to to the stack of segment identifiers;
the node advertising the first ID to other nodes in a network of nodes.

Abstract
An apparatus and method for path creation element driven dynamic setup of forwarding adjacencies and explicit path. In one embodiment of the method, a node receives an instruction to create a tunnel between the node and another node. The node creates or initiates the creation of the tunnel in response to receiving the instruction, wherein the tunnel comprises a plurality of nodes in data communication between the node and the other node. The node maps a first identifier (ID) to information relating to the tunnel. The node advertises the first ID to other nodes in a network of nodes.
