12. A method associated with a Segment Routing network that utilizes Flexible Algorithm, the method comprising steps of:
responsive to a Flex Algo Definition (FAD) of an auto-mesh plane, providing an advertisement of a Prefix Segment Identifier (SID) for a node in the auto-mesh plane;
including a flag in the advertisement designating whether the node is a destination node or a non-destination node in the auto-mesh plane; and
checking the flag in a received advertisement associated with another node, and, when the node is a destination node which requires transport connectivity based on the flag in the received advertisement, automatically creating transport or triggering the transport to the another node in the auto-mesh plane, wherein the transport includes an encapsulated tunnel between the node and the another node.
