    Abstract: An autonomous system (AS) pair verification method, apparatus, and device are disclosed. The method can avoid incorrectly 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 and 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: In a route processing method, a first network device obtains one or more routes having a same destination address, and including a first route. Slice information corresponding to the one or more ports is determined based on one or more ports that are on the first network device and that receive the one or more routes. The first network device sends an updated first route to a second network device, where the updated first route carries the slice information and the destination address. After a route is received, corresponding slice information is determined based on a port that receives the route, so that slice information supported by a path from a network device to a route starting device is determined. The determined slice information is carried when the route is forwarded, so that a network device on a route advertisement path can obtain the slice information supported by the entire path.

    Abstract: An IPv6 packet processing method and apparatus where a first routing device obtains an IPv6 packet, and sends the IPv6 packet to a next-hop routing device. The IPv6 packet includes an IPv6 extension header that includes preceding general indication information, where the preceding general indication information includes first information, and where the first information is used to indicate to process the IPv6 packet only on a data plane of a routing device and not to send the IPv6 packet to a CPU.

    Abstract: Embodiments of this application disclose a routing method and a related device. When a first network device determines that a preset first condition is met, the first network device sends a request message to a second network device, to request a route reaching at least one another network device. In response to the request message, the second network device sends a route message to the first network device serving as a traffic sender, where the route message carries the route reaching the at least one another network device, and both the first network device and the another network device are directly or indirectly connected to the second network device.

    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.
