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: In a packet sending method, a first network device receives a first multicast packet, and determines first information based on the first multicast packet, where the first information indicates an attribute of the first multicast packet. The first network device determines that a state of a first link interface is unavailable, and performs a modulo operation on the first information based on a second parameter, to obtain second indication information, where the second indication information indicates a second link interface through which the first network device forwards the first multicast packet, the second parameter is a quantity of link interfaces whose states are available in a first load balancing group, and the first load balancing group includes the first link interface and the second link interface. The first network device forwards the first multicast packet through the second link interface.

Abstract: A reverse path forwarding (RPF) check method includes, after receiving a multicast data packet from a head node, a tail node may obtain a multicast source address, a multicast group address and encapsulation information that are carried in the multicast data packet. The tail node obtains, based on the multicast source address, the multicast group address, and a first correspondence, a first identifier identifying an upstream multicast hop (UMH) node corresponding to the multicast data packet. The tail node may further obtain, based on the encapsulation information of the multicast data packet and a second correspondence, a second identifier identifying the head node corresponding to the multicast data packet. After obtaining the first identifier and the second identifier, the tail node may perform an RPF check based on the first identifier and the second identifier.

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 destination node device starts a timer when the destination node device determines that a network topology changes; before the timer expires, the destination node device forwards the BIER packet by using an old forwarding table and establishes a new forwarding table, where the old forwarding table is a forwarding table used by the destination node device before the network topology changes, the new forwarding table is a forwarding table established by the destination node device based on the changed network topology; and after the timer expires, the destination node device switches the old forwarding table to the new forwarding table, and forwards the BIER packet according to the new forwarding table.

Abstract: A multicast forwarding method applied to a BIER multicast network includes establishing, by a head node device, a first tunnel; generating a first entry; obtaining bit string information of a first multicast stream, where the bit string information includes an identifier of a tail node device that the first multicast stream is expected to reach; determining whether first bit string map information includes the identifier, in the bit string information, of the tail node device that the first multicast stream is expected to reach; and forwarding, by the head node device, the first multicast stream to a first intermediate node device through the first tunnel when the head node device determines that the first bit string map information includes the identifier in the bit string information, of the tail node device that the first multicast stream is expected to reach.
