Method, device and system for processing IPV6 messages

摘要

The present invention discloses a method, device, and system for processing an IPv6 packet, and relates to the field of Internet technologies. According to the present invention, a secure access, authentication, and authorization can be ensured in an IPv6 network, and different IPv6 address prefixes are allocated to different terminals. Therefore, normal routing in the network is ensured. A method for processing an IPv6 packet provided in an embodiment of the present invention includes: adding access line information or vendor information to an IPv6 packet; and forwarding the IPv6 packet that is added with the access line information or the vendor information; receiving an IPv6 packet that carries access line information or vendor information to obtain the access line information or the vendor information; and searching for a correspondence according to the access line information and the vendor information, so as to perform a corresponding operation on the IPv6 packet. The present invention is applicable to a scenario of processing a packet in an IPv6 network.
