Claim Text:
1. An apparatus, comprising: an aggregation network node including a processor and a communications interface, the aggregation network node configured to send, to a core network node, a request to associate with a native multicast group a first client device (1) coupled to the aggregation network node via a first access network node and (2) associated with a first Virtual Local Area Network (VLAN), the aggregation network node configured to send, to the core network node, a request to associate with the native multicast group a second client device (1) coupled to the aggregation network node via a second access network node and (2) associated with a second VLAN, the aggregation network node configured to receive a first instance of a multicast data unit associated with the native multicast group from the core network node, the aggregation network node configured to define, based on the first instance of the multicast data unit, a second instance of the multicast data unit and a third instance of the multicast data unit, the aggregation network node configured to send the second instance of the multicast data unit to the first access network node based on the first client device being associated with the first VLAN that is a member of a multicast network segment group, the aggregation network node configured to send the third instance of the multicast data unit to the second access network node based on the second client device being associated with the second VLAN that is a member of the multicast network segment group.
