The invention discloses a traffic forwarding method, device and system. The method includes the following steps that when a link, connected with a traffic receiving device, of a member device breaks down, a first synchronous message including DR port fault states of the member device is sent to other member devices in a DR group, and the first synchronous message is used for informing the other member devices of the DR port states of the member device; the member devices which do not break down in the DR group are determined, agent member devices used for traffic forwarding are determined fromthe member devices which do not break down, and according to the actual IP addresses of the agent member devices, a first route is generated; traffic sending equipment is informed of the first route,the first route is used for the DR port states of the member device, and the traffic sending equipment is used for forwarding the traffic forwarded by the member device through a tunnel between the traffic sending equipment and the agent member device. According to the traffic forwarding method and the device, the situation that the IPL chain causes loss of the service messages because of bandwidth deficiency is reduced, and the forwarding reliability is improved.
