Abstract

Embodiments of the invention relate to the field of the multicast network. Disclosed by the embodiments of the present invention are a method of establishing a bidirectional forwarding detection (BFD) session based on bit index explicit replication (BIER), a BFIR, a BFER, a system and a storage medium. A method includes: establishing, by a bit-forwarding ingress router (BFIR), the BFD session; flooding, by the BFIR, BFD information to a bit-forwarding egress router (BFER) group based on an Interior Gateway Protocol (IGP); and transmitting, by the BFIR, a BFD control packet to a BFER, to trigger the BFER to establish the BFD session corresponding to the BFIR.
