Abstract
In a route processing method, a first network device obtains one or more routes having a same destination address, and including a first route. 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.
