Abstract: A method applicable to a commonest application scenario, the method includes: an AR receives a first packet sent in a unicast manner by a CGN. The first packet includes information for indicating Restart announce, the first packet's source address is the CGN's address, and the first packet's destination address is the AR's address; AR changes the first packet's destination address to an address of a CPE connected to the AR, to obtain a second packet, where the AR and the CPE are connected by using a Layer 2 network, and the CPE's address is a multicast address; and the AR sends the second packet. The method is used for quickly informing, after the CGN restarts or undergoes an active/standby switchover, the CPE that an exception occurs, for example, the CGN restarts or undergoes an active/standby switchover, so that a CGN has relatively small load when recreating NAT mapping.

Abstract: The embodiments of the present invention provide a method, a device, and a system for forwarding a packet. The method includes: receiving an IPv6 packet sent by a gateway, and obtaining a flow label of the IPv6 packet, where the flow label of the IPv6 packet is corresponding to a link identity of customer premise equipment in one-to-one correspondence; decapsulating the IPv6 packet; performing network address translation on a decapsulated packet according to the flow label; and forwarding the decapsulated packet according to a translated network address. When multiple links between the gateway and an AFTR are corresponding to the same tunnel for network address translation, in the case that IP addresses of terminal users are overlapping or are the same, different terminal users can be distinguished, so that a terminal user that sends a packet can receive feedback, thus improving customer satisfaction.
