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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of establishing bidirectional forwarding detection session based on BIER, and BFIR, BFER, system and storage medium","description":"Embodiments of the invention relate to the field of the multicast network.
