Abstract
Supporting a scalable and Highly Available (HA) virtual Cable Modem Termination System (vCMTS). A software component receives, from the vCMTS, an update about a particular cable modem (CM) or customer premises equipment (CPE). The update may be sent in response to the particular CM or CPE becoming online or offline. In response to receiving the update, the software component provides, to at least one edge router, route data for the particular CM or CPE. The route data informs the edge router of a next hop network address for a network address of the particular CM or CPE. The edge router is not and need not be provided with either (a) any Address Resolution Protocol (ARP) data for the particular CM or CPE and (b) any Neighbor Discovery (ND) data for the particular CM or CPE.
