Abstract: A method for identifying a first hop router (“FHR”) in a distributed virtualized network is presented. In an embodiment, a method comprises receiving a multicast message on an incoming interface. In response to receiving the multicast message, the router determines whether the router is a FHR for the multicast message, i.e., whether, in response to generating and transmitting a hello multicast message, the router does not receive a response on the incoming interface; or whether an interface to a RP for the multicast message is different than the incoming interface. If the router is the FHR for the multicast message, then the router determines an IP address of a RP for the multicast message. The router also encapsulates the multicast message into a unicast message, includes in the unicast message the IP address of the RP as a destination address, and transmits the unicast message to the RP.
