Abstract
A method is provided in one example and includes determining that an access concentrator has lost customer premise equipment information. The method also includes obtaining the customer premise equipment information that is lost by evaluating Neighbor Discovery data and dynamic host configuration protocol version six (DHCPv6) query data. In more specific implementations, the method may include communicating a Bulk Leasequery message; receiving a response to the Bulk Leasequery message; and filtering out cable modem identifiers from the response to the Bulk Leasequery message.
