METHOD FOR CONFIGURING DHCPV6 CLIENT, DHCPV6 CLIENT, NETWORK DEVICE, AND NETWORK SYSTEM

摘要

A method for configuring a DHCPv6 client is provided. The method includes: a DHCPv6 client receiving a DHCPv6 advertisement message sent by a network device having a DHCPv6 function, the DHCPv6 advertisement message comprising a management domain identifier of the network device; if the DHCPv6 client does not save the management domain identifier, the DHCPv6 client sending a DHCPv6 request message to the network device; the DHCPv6 client receiving a DHCPv6 response message sent by the network device and completing configuration of the DHCPv6 client. A DHCPv6 client, a network device, and a network system are also provided. Through the technical solution, multiple network devices supporting a DHCPv6 server function can configure the same DHCPv6 client, so as to provide technical support for realizing IPv6 client and network multi-homing.

1. A method for configuring a Dynamic Host Configuration Protocol for Internet Protocol version 6 (DHCPv6) client, the method being applied to a network with the DHCPv6 client and a network device functioning as a DHCPv6 server, wherein the method comprises:
receiving, by the DHCPv6 client, a DHCPv6 advertise message from the network device, wherein the DHCPv6 advertise message comprises a management domain identifier of the network device; sending, by the DHCPv6 client, a DHCPv6 request message to the network device and storing the management domain identifier, when the DHCPv6 client does not save the management domain identifier; and receiving, by the DHCPv6 client, a DHCPv6 reply message from the network device and configuring the DHCPv6 client according to the DHCPv6 reply message, wherein the DHCPv6 reply message comprises an IPv6 prefix assigned to the DHCPv6 client by the network device and a network configuration parameter assigned to the DHCPv6 client by the network device; or the DHCPv6 reply message comprises an IPv6 address assigned to the DHCPv6 client by the network device and a network configuration parameter assigned to the DHCPv6 client by the network device.
