A fiber-coax unit (FCU) is coupled to an optical line terminal (OLT) and a plurality of coax network units (CNUs). The FCU receives a multicast frame from the OLT. The multicast frame includes a first multicast logical link identifier (LLID) dedicated for multicast traffic directed to CNUs. The FCU replaces the first multicast LLID in the multicast frame with a second multicast LLID corresponding to one or more multicast groups that include at least one CNU of the plurality of CNUs. The FCU transmits the multicast frame to the plurality of CNUs.
