    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: 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.

    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.
