Abstract

The invention provides an IPv6 address allocation method and device. The method comprises the steps of: after receiving a DHCPv6 request message sent by terminal equipment, generating a relay-forwardmessage, wherein the source IPv6 address of the relay-forward message is the IPv6 address of the management interface of a distributed gateway; and the appointed field of the relay-forward message carries the IPv6 address of the VSI interface of the distributed gateway; sending the relay-forward message to a DHCPv6 server, and receiving a relay-reply message sent by the DHCPv6 server, wherein thedestination IPv6 address of the relay-reply message is the IPv6 address of the management interface of the distributed gateway; and furthermore, the relay-reply message carries the IPv6 address, whichis allocated to the terminal equipment by the DHCPv6 server according to the IPv6 address of the VSI interface of the distributed gateway; and, sending the IPv6 address, which is allocated to the terminal equipment, to the terminal equipment. By means of the technical scheme in the invention, the IPv6 address can be successfully allocated to the terminal equipment.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an IPv6 address allocation method and device. Background technique [0002] With the rapid development of Internet applications, the number of Internet users is increasing, but the network address resources of IPv4 (Internet Protocol Version 4, Internet Protocol Version 4) addresses are limited, which seriously restricts the application and development of the Internet. For this reason, IPv6 (Internet Protocol Version 6, Internet Protocol Version 6) addresses can be used to replace IPv4 addresses, thereby solving the problem of limited network address resources. [0003] In an IPv6 network, a DHCPv6 (Dynamic Host Configuration Protocol for IPv6, a dynamic host configuration protocol supporting IPv6) server can be deployed, and the DHCPv6 server assigns an IPv6 address to a terminal device. When the terminal device and the DHCPv6 server are not in the same net...
