Abstract: A method and apparatus are provided. The method includes: a first network device sends route information of a destination network device, where the route information includes a destination address of the destination network device, a primary next-hop address, and a backup next-hop address, the primary next-hop address includes a common address of the first network device and a second network device, for example, a loopback address, and the backup next-hop address includes an address of the first network device, for example, an IP address of the first network device. By using this method, when a fault occurs in a connection between the second network device and the destination network device, another network device may directly send a packet to the first network device according to the backup next-hop address, to ensure normal packet forwarding.

Abstract: A BGP route identification method and apparatus are provided. A network device obtains a BGP route. The BGP route includes an autonomous system path attribute AS_PATH attribute, the AS_PATH attribute includes a first autonomous system number AS number, an AS number corresponding to an autonomous system that the network device is located in or manages is a second AS number, and the first AS number is equal to the second AS number. The network device determines, based on the first AS number and the second AS number, whether the BGP route is abnormal.

Abstract: In a method for managing a VPN, a routing device establishes a BMP session with a BMP server. The routing device allocates a VPN label associated with a VPN instance, wherein the VPN instance is used for communication between the routing device and another routing device. Then, the routing device sends, to the BMP server, a BMP message that carries the VPN label. Because the routing device sends the VPN label through the BMP message, the routing device does not need to establish a BGP peer relationship with the BMP server to send the VPN label.

Abstract: A packet sending method includes, after determining to send a packet based on a non-shortest path and determining that a second network device and a first network device on the non-shortest path belong to different groups, the first network device may send the packet to the second network device, and notify the second network device to send the packet based on a shortest path. After receiving the packet, the second network device may send the packet based on the shortest path, and notify another network device on the shortest path to send the packet based on the shortest path. In this way, in a process of sending the packet, after the packet passes through an inter-group path in the non-shortest path, a remaining path is the shortest path for sending the packet to a destination device.
