Abstract: A device may provide information associated with initiating a segmented tunnel to be used to transfer multicast traffic via a network covering a plurality of areas. The device may receive acknowledgement information associated with the segmented tunnel. The acknowledgement information may include information that identifies a number of egress devices, associated with at least one area of the plurality of areas, that are to receive the multicast traffic. The device may determine, based on the acknowledgement information, a total number of egress devices that are to receive the multicast traffic. The device may selectively provide the multicast traffic via the segmented tunnel based on the total number of egress devices that are to receive the multicast traffic.

Abstract: A first device may receive a traffic flow to be multicasted to at least two of a set of second devices. The first device may provide first messages to the set of second devices identifying the traffic flow. The first device may identify a set of interested second devices, of the set of second devices, based on respective second messages that are received from the set of interested second devices based on the first messages. The first device may determine whether a quantity of the set of interested second devices satisfies a threshold. The first device may selectively provide the traffic flow to the set of interested second devices, using a first type of multicast distribution tree or a second type of multicast distribution tree, based on whether the quantity satisfies the threshold.
