1. A non-transitory computer-readable medium having instructions stored thereon for programming a node in a Segment Routing network to perform steps of:
responsive to what services are support at the node, creating a bitmap to represent the plurality of services supported at the node; and
transmitting an advertisement with the bitmap such that the advertisement is a single advertisement of multiple services,
wherein the bitmap includes a first-bit location that corresponds to a specific start representing a first service and each bit location that follows represents following services in sequence, and wherein each bit in the bitmap is set based on the services that are supported at the node.
