Embodiments of this application disclose an information reporting method, an information processing method, and a device. According to the information reporting method, a network device obtains Border Gateway Protocol (BGP) information of a network device. The network device sends a BGP Monitoring Protocol (BMP) notification message to a first device, where the BMP notification message carries the BGP information of the network device.

Information reporting method, information processing method, and device

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.

BGP route identification method, apparatus, and device

A method for updating route information includes a monitored network element establishes a Border Gateway Protocol (BGP) Monitoring Protocol (BMP) connection to a monitoring network element, and sends a first message to the monitoring network element when detecting a synchronization requirement of BGP route information, where the first message instructs the monitoring network element to update a BGP route information set, and the BGP route information set includes at least one piece of BGP route information. The first message indicates an update set, and the update set updates the BGP route information set.

Method and apparatus for updating route information, computer device, and storage medium

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.

AS pair verification method, apparatus, and device

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.

Information reporting method, data processing method, and apparatus

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.

Traffic processing method, apparatus, and network device

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.

Information reporting method, information processing method, apparatus, and device

This application provides a route event record entry processing method, a network device, and a control device. The method includes: obtaining, by a network device, first information and second information that correspond to a route prefix, where the first information is used to indicate information about a first route policy for the route prefix, and the second information is used to indicate attribute information obtained after processing the route prefix by using the first route policy; and generating, by the network device, a route event record entry for the route prefix based on the first information and the second information, where the route event record entry includes the route prefix, the first information, and the second information.

Entry processing method, network device, and control device

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.

Method for managing virtual private network, and device

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.
