Abstract: This application relates to the field of computer network technologies and discloses an autonomous system (AS) pair verification method, apparatus, and device. The method can avoid incorrect determining of an AS pair in path information of an AS path during verification of the AS path, and improve accuracy of verifying the AS path. The method is applied to a network device. The method includes: obtaining path information including an AS pair; determining region information of a region to which the AS pair in the path information belongs; and verifying the AS pair based on the determined region information of the region to which the AS pair belongs, where the AS pair in the path information includes two adjacent AS numbers in the path information.

Abstract: This disclosure discloses a method, device, and system for determining a route leak. The method includes: receiving, by a network monitoring device managing a first autonomous system, an extended BMP packet sent by a first border node of the first autonomous system and an extended BMP packet sent by a second border node of the first autonomous system. The method includes determining, based on the extended BMP packet sent by the first border node and the extended BMP packet sent by the second border node of the first autonomous system, a receiving relationship of a route prefix received by the first border node from the second autonomous system, and a sending relationship of the route prefix sent by the second border node to a third autonomous system. The method further includes determining, based on the receiving relationship and the sending relationship, whether the route prefix is leaked.

Abstract: Embodiments of this application disclose a method for determining route flapping information, to determine route flapping information based on parameter information reported by a routing device. The method in the embodiments of this application includes the following steps: receiving parameter information sent by each of at least one routing device, where parameter information sent by any routing device includes at least one of protocol packet information, count information, and identity identification information of the any routing device; and determining route flapping information of a target routing device based on the parameter information sent by each of the at least one routing device, where the target routing device is one of the at least one routing device.
