Abstract:
Methods, apparatus, and articles of manufacture to provide a multicast virtual private network (MVPN) are disclosed. Example methods to transmit multicast data in a network disclosed herein include monitoring, with 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. Disclosed example methods also include, after the switch to the second logical topology, accessing a multicast data packet associated with a first multicast route generated for the multicast data flow from a second network node, 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.
