Abstract: A computer readable medium, configuration server, and configuration system for receiving and processing a subscriber node address request is provided. A bridge service module provides a predetermined bridging criterion to a bridge extension module, the bridge extension module makes a bridging determination based on the bridging criterion and the subscriber node address request and provides a bridging message based on the subscriber node address request, when a result of the bridging determination indicates that the bridging message is to be provided. The configuration server may be a DHCP server in cable network environment, such that a cable modem receives an IP address and configuration data responsive to the subscriber node address request from a second DHCP server to which the bridging message is transmitted.
