Problems solved by technology

[0005] In a related technical solution, the service identifier (used to identify the VPN instance) is carried in the MPLS label. Since the BIER message contains an MPLS label layer, it is impossible to realize the de-MPLS of the entire network, which adds additional complexity to the device. sex

Abstract

The invention provides a method, equipment and system for forwarding a BIER message, and the method comprises the steps that a first network device receives a BIER message sent by a second network device, wherein the BIER message comprises an IPv6 header, a BIER header and a multicast message, a destination address of the IPv6 header or a first field of the BIER header carrying a service identifier, wherein the service identifier is used for identifying a virtual private network (VPN) instance; the first network device determines a VRF table according to the service identifier and a first corresponding relationship, wherein the first corresponding relationship comprises a corresponding relationship between the service identifier and the VRF table; and the first network device sends a multicast message to first customer edge (CE) equipment in the VRF table according to the VRF table. According to the technical scheme provided by the invention, the implementation is relatively simple when the VPN instance is identified by an exit edge device.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202010702525.5 and the title of the invention "a multicast forwarding method, device and system" submitted to the China Patent Office on July 21, 2020, the entire contents of which are incorporated herein by reference In this application. technical field [0002] The present application relates to the field of network communication, and more specifically, relates to a method, device and system for message forwarding. Background technique [0003] The internet protocol (internet protocol, IP) multicast technology realizes efficient point-to-multipoint data transmission in an IP network, and can effectively save network bandwidth and reduce network load. For this reason, the industry has proposed a new technology for constructing multicast packet forwarding paths, called bit indexed explicit replication (BIER) technology, which proposes a new technology that does not requi...
