Abstract: A packet forwarding method and device, and a system are provided, and belong to the field of communication technologies. The method includes: A first node first receives a route to a destination node sent by a second node, where the route carries an identifier of the second node and a plurality of tunnel attributes. A plurality of tunnels from the first node to the second are in a one-to-one correspondence with the plurality of tunnel attributes. The first node forwards packets with different packet attributes destined for same destination node through different tunnels. In this application, packets having different packet attributes can be forwarded over different tunnels, so that traffic steering is implemented at a routing layer, and flexibility of packet forwarding is improved.
