The embodiments of the present disclosure provide a data packet processing method and apparatus, a storage medium and an electronic device. The method includes that: a Bit Index Explicit Replication (BIER) Multicast Identifier (BMID) information of a data packet is set, wherein the BMID information is used for indicating a multicast channel to which the data packet belongs; and the BMID information is sent to a Bit-Forwarding Ingress Router (BFIR). Through the solution in the embodiments of the present disclosure, the technical problem in the related art that a node receives duplicate data packets is solved, duplicate data packets may be prevented, and data transmission efficiency is improved.
