A forward entry generating method, comprising: receiving, by a first forward node, MPLS forwarding path information, which is sent by a Controller, of a Multiprotocol Label Switching, MPLS, forwarding path, wherein the MPLS forwarding path information comprises: ingress node information, transit node information, and egress node information; sending the MPLS forwarding path information to a third forward node; and generating an MPLS forward entry of the first forward node according to the MPLS forwarding path information, wherein the generating an MPLS forward entry of the first forward node according to the MPLS forwarding path information comprises: determining, according to any information of the ingress node information, the transit node information, and the egress node information that are in the MPLS forwarding path information, whether the first forward node is comprised in the MPLS forwarding path; and when determining that the first forward node is comprised in the MPLS forwarding path, generating the MPLS forward entry of the first forward node according to the MPLS forwarding path information; wherein the MPLS forwarding path information further comprises a path Identity, ID, of the MPLS forwarding path; and wherein the determining, according to any information of the ingress node information, the transit node information, and the egress node information that are in the MPLS forwarding path information, whether the first forward node is comprised in the MPLS forwarding path comprises: determining whether MPLS forwarding path record information of the first forward node comprises the path ID, wherein the MPLS forwarding path record information is used to record a path ID of an MPLS forwarding path corresponding to an MPLS forward entry that is already generated by the first forward node; and when determining that the MPLS forwarding path record information of the first forward node does not comprise the path ID, determining, according to any information of the ingress node information, the transit node information, and the egress node information that are in the MPLS forwarding path information, whether the first forward node is comprised in the MPLS forwarding path. receiving, by a first forward node, MPLS forwarding path information, which is sent by a Controller, of a Multiprotocol Label Switching, MPLS, forwarding path, wherein the MPLS forwarding path information comprises: ingress node information, transit node information, and egress node information;
