Abstract
The present invention discloses a forward entry generating method, a forward node, and a controller. The method includes: receiving, by a first forward node, MPLS forwarding path information, which is sent by a controller, of a MPLS forwarding path, where the MPLS forwarding path information includes: 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. According to the method, the forward node, and the controller in embodiments of the present invention, it can be avoided that the controller sends, in a point-to-point manner, MPLS forward entries to all forward nodes that an MPLS forwarding path passes through, thereby effectively improving efficiency of generating an MPLS forward entry and reducing occupation of outbound bandwidth of the controller.
