Embodiments of this disclosure include a packet forwarding method and device, and a related system, and belong to the field of communication technologies. In the method, 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 a same destination node through different tunnels. By having the packets with the different packet attributes forwarded over the different tunnels, traffic steering is implemented at a routing layer, and a flexibility of performing the packet forwarding is improved.

A first network device obtains first information. The first information indicates that a first link is faulty, and the first link is a link between any two network devices in a network system to which the first network device belongs. The first network device sends the first information to a second network device by using BGP, for example, sends a link fault message to the second network device by using BGP. The link fault message carries the first information. The second network device is a neighbor device of the first network device. The first network device determines an unreachable route in a routing table of the first network device based on the first information and a topology of the network system. A path corresponding to the unreachable route includes the first link. The first network device marks the unreachable route as invalid.

Slice information corresponding to the one or more ports is determined based on one or more ports that are on the first network device and that receive the one or more routes. The first network device sends an updated first route to a second network device, where the updated first route carries the slice information and the destination address. After a route is received, corresponding slice information is determined based on a port that receives the route, so that slice information supported by a path from a network device to a route starting device is determined. The determined slice information is carried when the route is forwarded, so that a network device on a route advertisement path can obtain the slice information supported by the entire path.
