Patent number: 8886834Abstract: Techniques are provided herein for receiving synchronization messages at a second network device that is in a hot standby configuration from a first network device that is maintaining Internet Protocol version 6 (IPv6) state machines for one or more neighbor devices. The synchronization messages are configured to indicate an IPv6 state for each state machine maintained in the first network device. An IPv6 state for corresponding state machines is updated in the second network device based on the synchronization messages such that the IPv6 states in the second network device allows the second network device to actively process IPv6 traffic for the one or more neighbor devices upon traffic switchover from the first network device to the second network device without restarting the corresponding IPv6 state machine associated with each of the one or more neighbor devices in the second network device. The roles of the first and second device with respect to active and standby state are reversed after a switchover.Type: GrantFiled: December 14, 2010Date of Patent: November 11, 2014Assignee: Cisco Technology, Inc.Inventors: Hemant Singh, William Beebee, Madhu Sudan

Publication number: 20140215091Abstract: In one embodiment, methods are described for recovering lost customer premises equipment (CPE) information on a cable modem termination system (CMTS) in the presence of only Dynamic Host Control Protocol Version 6 (DHCPv6) CONFIRM. A CMTS purges routing information for an Internet Protocol Version 6 (IPv6) node, such as a CPE router, in response to detecting an interface reset for the IPv6 node. IPv6 addresses and prefixes information for the IPv6 node is gleaned from a DHCPv6 CONFIRM message received from the IPv6 node. By sending portions of the IPv6 addresses and prefixes information within a DHCPv6 LEASEQUERY message, a DHCPv6 CONFIRM message with an embedded DHCPv6 LEASEQUERY message, or a DHCPv6 CONFIRM message with an Interface-ID option, a reply message can be received that contains the purged routing information for the IPv6 node.Type: ApplicationFiled: January 31, 2013Publication date: July 31, 2014Applicant: CISCO TECHNOLOGY, INC.Inventors: Hemant Singh, William Beebee, Madhu Sudan, Bernard E.

Patent number: 8437360Abstract: A CMTS or other data aggregation component having a DHCPv6 relay agent extracts a Media Access Control (MAC) address of an end device from a data packet received from an end device. A DHCPv6 data frame is created for transmission to a DHCPv6 server. The MAC address may be inserted into a specific option of the DHCPv6 data frame, where data in the option may not be processed by the server and are echoed back to the aggregation component or CMTS. The DHCPv6 data frame is transmitted to the DHCPv6 server. The component receives a response message from the server that may contain the MAC address or similar client hardware address as it was sent to the server by the network component. The network component may determine an outgoing port interface from which the response message should be sent, utilizing the MAC address and an interface bundling table. In this manner, interface bundling may be enabled.Type: GrantFiled: November 14, 2007Date of Patent: May 7, 2013Assignee: Cisco Technology, Inc.Inventors: Hemant Singh, Madhu Sudan, Shengyou Zeng
