Claim 9:
10. The data packet processing method according to claim 4, further comprising:
in response to a second final data packet with the second predetermined format sent by another PE node in a network, determining the identification information of the ingress node of the context virtual circuit corresponding to the received second final data packet according to the virtual circuit label in the received second final data packet, wherein the identification information is used for at least one of the following:
recording the determined identification information of the ingress node as the identification information of an ingress PE node of the received second final data packet;
when the current PE node is about to forward the received second final data packet to the ingress node of the context virtual circuit, discarding the second final data packet; and
when the current PE node is about to forward the received second final data packet to any remote PE node in a split horizon group to which the ingress node of the context virtual circuit belongs, discarding the second final data packet.
