Abstract
Systems and methods include obtaining a plurality of services supported at the node; determining a bitmask to represent the plurality of services supported at the node, wherein the bitmask includes a starting service and each subsequent bit representing another service of the plurality of services and with each bit in the bitmask set based on the plurality of services supported at the node; and transmitting an advertisement to nodes in the Segment Routing network with a starting Service SID value and the bitmask based on the plurality of services supported at the node. The plurality of services can include any of a Virtual Private Wire Service (VPWS) and a Flexible Cross Connect (FXC) service.
