The method applied to an Ingress PE includes: determining, in an Ethernet virtual private network instance (EVI), that a state of the EVI on a first Egress PE is Active, where an Ethernet virtual private network (EVPN) corresponding to the EVI includes a first customer edge (CE); determining that a state of the EVI on a second Egress PE is Inactive; skipping, forwarding a broadcast, unknown unicast, and multicast (BUM) packet to the second Egress PE, where the BUM packet is from the first CE; and forwarding, the BUM packet to the first Egress PE. According to the application, repeated BUM traffic that is transmitted in a bearer network and is not finally sent to a remote site is reduced; therefore, a waste of bandwidth in the bearer network is reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Packet forwarding method, apparatus, and system","description":"A packet forwarding method, a packet forwarding system, and a provider edge (PE) device.
