Methods, apparatus, and articles of manufacture to provide a multicast virtual private network (MVPN)

A non-transitory computer readable medium including computer readable instructions that, when executed by a processor of a first network node, cause the processor to perform operations comprising:

• monitoring a multicast data flow to determine a characteristic for triggering a switch from a first logical topology for the multicast data flow to a second logical topology for the multicast data flow;
• and
• after the switch to the second logical topology:
• accessing a multicast data packet from a second network node, the multicast data packet associated with a first multicast route generated for the multicast data flow;
• and
• transmitting a first replication of the multicast data packet to a third network node via a unicast path, the first replication of the multicast data packet to include a first label provided by the third network node to identify the first multicast route.

A method to transmit multicast data in a network, the method comprising:

• monitoring, by executing an instruction with a processor of a first network node, a multicast data flow to determine a characteristic for triggering a switch from a first logical topology for the multicast data flow to a second logical topology for the multicast data flow;
• and
• after the switch to the second logical topology:
• accessing, by executing an instruction with the processor, a multicast data packet from a second network node, the multicast data packet associated with a first multicast route generated for the multicast data flow;
• and
• transmitting a first replication of the multicast data packet to a third network node via a unicast path, the first replication of the multicast data packet to include a first label provided by the third network node to identify the first multicast route.
