Aiming at the problem appeared when preventing IP cheating in access node equipment of IPv6 access network, a method and system for transferring packet in IPv6 access node are provided and used for transferring packet from residential gateway. The method comprises: firstly, the access node equipment receives the packet from residential gateway; secondly, obtaining network prefix in source IPv6 address of the packet; then, judging whether the network prefix in source IPv6 address of the packet is a valid network prefix of client premises network corresponding to the residential gateway; finally, if yes, transferring the packet. Especially the access node equipment can automatically obtain valid network prefix by technical means such as listening to network prefix distributing response message, therefore safty and operating efficiency of IPv6 are obviously improved and network management of IPv6 access network is simplified. |
