    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: This application provides a packet sending method, a network device, and a system. The method includes: A first network device receives an advertisement message sent by a second network device, where the advertisement message includes segment routing policy SR policy information and traffic feature information, and the SR policy information includes a segment identifier list SID list. The first network device establishes a correspondence between the traffic feature information and the SID list according to the advertisement message, where the correspondence is used to guide forwarding of a packet including the traffic feature information.

    Abstract: This application provides an information processing method. A first communication apparatus is configured with a BGP EPE function, a BGP session is established between the first communication apparatus and a third communication apparatus, and no BGP session is established between the first communication apparatus and a second communication apparatus. In this case, the first communication apparatus may obtain, by using the third communication apparatus, a route advertised by the second communication apparatus. The next hop of the route is the second communication apparatus. After receiving the route, the first communication apparatus allocates a BGP peer SID, and stores a correspondence between the BGP peer SID and the next hop. When receiving a packet including the BGP peer SID, the first communication apparatus may forward the packet to the next hop based on the correspondence.

    Abstract: A method and apparatus are provided. The method includes: a first network device sends route information of a destination network device, where the route information includes a destination address of the destination network device, a primary next-hop address, and a backup next-hop address, the primary next-hop address includes a common address of the first network device and a second network device, for example, a loopback address, and the backup next-hop address includes an address of the first network device, for example, an IP address of the first network device. By using this method, when a fault occurs in a connection between the second network device and the destination network device, another network device may directly send a packet to the first network device according to the backup next-hop address, to ensure normal packet forwarding.

    Abstract: Embodiments of the present disclosure provide a routing control method, network device, and controller. The method may include the network device obtaining a route suppression request. The method may also include determining the second routing entry. Furthermore, the method may include setting a state of the second routing entry to a non-delivery state that is used to indicate that the second routing entry does not need to be delivered to a forwarding table. In the method, the network device may have a first routing entry and a second routing entry, an address prefix of the first routing entry is a first address prefix, an address prefix of the second routing entry is a second address prefix, a network segment to which the second address prefix belongs is a subset of a network segment to which the first address prefix belongs, and a mask in the second address prefix is greater than a mask in the first address prefix.
