Abstract: This application provides a packet sending method. The method includes: receiving, by a first network device, a data packet, and encapsulating the data packet to obtain a first packet, where the first packet includes an IPv6 header, a bit index explicit replication BIER header, and the data packet, and some bits of a source IPv6 address field in the IPv6 header include identification information of a first tenant; and sending, by the first network device, the first packet to a second network device, where the identification information of the first tenant is used by the second network device to determine to send the data packet to an interface, corresponding to the first tenant, of the second network device.

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: 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.

Abstract: 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.

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: A packet processing method includes a second device that sends a first packet to a first device, where the first packet includes a first segment routing header (SRH). After receiving the first packet, the first device determines whether the first packet includes a first segment identifier. When the first packet includes the first segment identifier, the first device deletes the first SRH, performs an encapsulation operation to generate a second packet, and forwards the second packet. That is, when a function or an indication corresponding to the first segment identifier is to perform the encapsulation operation, after receiving the first packet, the first device may delete the first SRH in the first packet based on an actual case, and perform the encapsulation operation to generate the second packet, where the second packet does not include the first SRH.
