Abstract
Techniques are generally directed to selective reestablishment of Internet Protocol (IP) connectivity between a cable modem and a cable modem termination system (CMTS). IP connectivity between the cable modem and the CMTS is initially established through execution of a plurality of connectivity steps. After IP connectivity is lost, the cable modem determines which of the plurality of connectivity steps are desired for use in reestablishing IP connectivity, and sends a message to the CMTS indicating the desired IP connectivity step. The CMTS determines if the desired connectivity steps identified in the message may be used to reestablish IP connectivity, and sends a response message to the cable modem indicating if the desired connectivity steps may be used. IP connectivity is then reestablished using at least the desired connectivity steps.
