Abstract
Disclosed is a packet forwarding method, comprising: receiving a packet to be sent to a bit-forwarding egress router (BFER) based on traffic engineering for bit index explicit replication (BIER-TE), and a path identifier, wherein the path identifier is used for indicating that the packet is sent from a first bit-forwarding router (BFR) to a primary path and a backup path of a next-hop BFR of the first BFR; determining, according to the path identifier, a bit string used for forwarding the packet to the BFER; and filling the bit string in the packet and forwarding the packet according to the bit string.
