Abstract
A method and apparatus for enabling congruent multicast and unicast routing in a Virtual Private Network (VPN) are disclosed. For example, the present method receives a request to join a multicast group to receive multicast data traffic by a receiver behind a remote Provider Edge (PE) router. The method then discovers a multicast source to allow said remote PE router to use a direct path to receive said multicast data traffic from a source.
