Abstract: In some embodiments, an apparatus includes a core network node configured to associate with a native multicast group a first client device that is associated with a first virtual local area network (VLAN) and operatively coupled to the core network node via a first access network node and an aggregation network node. The core network node can associate with the native multicast group a second client device that is associated with a second VLAN and operatively coupled to the core network node via a second access network node and the aggregation network node. The core network node can define a multicast VLAN including the first VLAN and the second VLAN based on the native multicast group. The core network node can receive a multicast data unit associated with the native multicast group and can also define a single instance of the multicast data unit for the multicast VLAN.
