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.

Abstract: When obtaining a first Border Gateway Protocol (BGP) route, a first network device may directly send the first BGP route to a second network device without recursing the first BGP route. Alternatively, the first network device recurses the first BGP route. The first network device still sends the first BGP route to the second network device when the first BGP route fails to be recursed. That is, regardless of whether the first network device performs recursion or if the recursion fails, the first network device can forward the received first BGP route to the second network device.
