摘要： A method includes a network device that obtains Border Gateway Protocol (BGP) route information, where the B GP route information includes a target route prefix; obtains, based on the target route prefix, a region identifier of a region to which the target route prefix actually belongs; and verifies the BGP route information based on the target route prefix and the region identifier of the region to which the target route prefix actually belongs.

摘要： A network device obtains Border Gateway Protocol (BGP) flow specification (FlowSpec) information, and generates, based on the BGP FlowSpec information, a first forwarding information base (FIB) table entry including a first prefix and an action, where the BGP FlowSpec information indicates to perform an action on traffic matching a filter condition, where the filter condition includes an attribute of a destination address, where the first FIB table entry indicates the network device to perform the action on the traffic matching the first prefix, and where an attribute of the first prefix is the same as the attribute of the destination address in the filter condition.

摘要： An information reporting method includes after receiving a Border Gateway Protocol (BGP) flow specification (FS) rule, a network node obtains a status of implementing the BGP FS rule on the network node, where the status indicates that either the BGP FS rule is implemented on the network node or the BGP FS rule is not implemented on the network node. Then the network node sends the status to a server.

摘要： A data packet detection method, a device, and a system are disclosed. The method includes: receiving first control information sent by a controller; receiving a first data packet sent by a previous-hop network device of a first network device, where the first data packet includes first detection information, and the first detection information includes a first detection node identifier, a first sequence number, and first collection information; determining, based on the first collection information, first collected data corresponding to the first collection information, and updating the first detection node identifier; and sending, to a next-hop network device of the first network device, the first data packet carrying the updated first detection information. This implements information telemetry on a data packet on a transmission path.

摘要： 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.

摘要： 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.

摘要： Embodiments of this application disclose an information reporting method, an information processing method, an apparatus, and a device. The method in embodiments of this application includes the network device obtains a routing prefix included in local routing information, and information about a neighboring peer set corresponding to the routing prefix, and sends a local route monitoring message including the routing prefix and the information about the neighboring peer set to a first device. The neighboring peer set includes a source peer set and/or a destination peer set, the source peer set includes one or more source peers, the source peer is a peer that advertises original routing information including the routing prefix to the network device, the destination peer set includes one or more destination peers, and the destination peer is a peer to which the network device advertises destination routing information including the routing prefix.
