1. A method performed at least partly by a Bit Index Replication (BIER) replicator node that is configured to implement a BIER protocol, comprising:
receiving, from a data source and at the BIER replicator node, a stream packet sent using the BIER protocol and that has a metadata-enabled header that indicates a replicator policy, wherein the stream packet further identifies a service-level cast group address of a service-level cast group;
determining that the replicator policy indicates that the stream packet is to be replicated;
replicating, via the BIER replicator node, the stream packet according to the BIER protocol to result in two or more replicated stream packets; and
transmitting, via the BIER replicator node, the two or more replicated stream packets to receiver nodes that are configured to implement BIER.
