Abstract
This application discloses a route advertisement method, a packet forwarding method, a device, and a system. A first network device obtains a first VPN route and a second VPN route that have a same route prefix and a same route distinguisher but different VPN identifiers and different next hops. The first network device allocates a third VPN identifier to the first VPN route and the second VPN route, and stores, on a forwarding plane, a first correspondence between the third VPN identifier and a first VPN identifier that is included in the first VPN route and a second correspondence between the third VPN identifier and a second VPN identifier that is included in the second VPN route. The first VPN route and the second VPN route that belong to a same VPN can form fast reroute or load balancing.
