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.

Abstract: The present disclosure discloses a method and an apparatus for controlling a network traffic path. The method includes: receiving routing advertisement information from a first network to a second network; determining all routing nodes included in a path through which data pass when flowing from the second network to the first network according to the routing advertisement information; and configuring a next hop routing node for each determined routing node, where the next hop routing node is a node in all the routing nodes included in the path and is adjacent to the routing node for which the next hop routing node is configured, and the routing node for which the next hop routing node is configured does not include a routing node of the first network or a routing node of the second network.

Abstract: A packet transmission method includes, obtaining one or more control items, a first network device determines, based on a fact that a device identifier included in a first packet to which each control item belongs is a device identifier of a second network device, a target control item to be sent to the second network device. The first network device sends at least one second packet comprising the target control item to the second network device, where the target control item is located in the at least one second packet, and the second packet includes the device identifier of the second network device.

Abstract: Disclosed is a portal push method, which comprises: a broadband remote access server (BRAS) equipment acquiring a website identification list, after the BRAS equipment receives a hypertext transport protocol (HTTP) request message sent by a user terminal. The BRAS equipment determines whether to send portal pages to the user terminal according to whether the identification of a target website visited by the user client has a matched item in the list. The embodiments of the present disclosure further provide a corresponding BRAS equipment. The technical solutions of the embodiments of the present disclosure can reduce push times of invalid portals and improve portal push success rate.

Abstract: This application provides an information processing method. A first communication apparatus is configured with a BGP EPE function, a BGP session is established between the first communication apparatus and a third communication apparatus, and no BGP session is established between the first communication apparatus and a second communication apparatus. In this case, the first communication apparatus may obtain, by using the third communication apparatus, a route advertised by the second communication apparatus. The next hop of the route is the second communication apparatus. After receiving the route, the first communication apparatus allocates a BGP peer SID, and stores a correspondence between the BGP peer SID and the next hop. When receiving a packet including the BGP peer SID, the first communication apparatus may forward the packet to the next hop based on the correspondence.
