Abstract
A method for load balancing in a bit index explicit replication (BIER) network includes: a network device obtains a BIER packet, and determines, based on an identifier in the BIER packet, a target next-hop node that reaches a destination address of the first BIER packet from a plurality of next-hop nodes of the network device. Then, the network device generates a target forwarding table based on the target next-hop node, and forwards the first BIER packet based on the target forwarding table. A control plane does not perform load balancing on a BIER packet in a manner of delivering a large quantity of load balancing tables to a forwarding plane, but the forwarding plane of the network device generates the target forwarding table to perform load balancing on the BIER packet.
