Support for a scalable and highly available (HA) service platform

Supporting a scalable and Highly Available (HA) service platform. The service platform may be a virtual Cable Modem Termination System (vCMTS), a Passive Optical Network (PON), or a Broadband Network Gateway (BNG). A software component receives, from the service platform, an update about a particular unit of equipment, such as a cable modem (CM), Optical Network Unit (ONU)/Optical Network Terminal (ONT), or customer premises equipment (CPE). In response to receiving the update, the software component provides, to at least one edge router, route data for the particular unit of equipment. The route data informs the edge router of a next hop network address for a network address of the unit of equipment. The edge router is not and need not be provided with either (a) any Address Resolution Protocol (ARP) data for the particular unit of equipment and (b) any Neighbor Discovery (ND) data for the particular unit of equipment.
