Abstract
Methods, apparatus, and articles of manufacture to provide a multicast virtual private network (MVPN) are disclosed. An example method to transmit multicast data over a communication network includes receiving, at a first machine, a multicast data packet from an ingress provider edge router of the communication network, the multicast data packet associated with a multicast route, and transmitting a first replication of the multicast data packet from the first machine to a second machine via a first unicast path. The first replication of the multicast data packet includes a first label provided by the second machine to identify the multicast route in the second machine. Example methods further include receiving the first replication of the multicast data packet at the second machine via the first unicast path, and replicating the multicast data packet from the second machine to an egress provider edge router of the communication network.
