Abstract
In one embodiment, a method is provided. The method includes determining that a network device should use an underlay multicast group associated with an overlay multicast group for multicast traffic. The underlay multicast group carries multicast traffic for the overlay multicast group. The overlay multicast group is associated with a virtual private network. The method also includes determining an underlay multicast group address for the underlay multicast group. The overlay multicast group is associated with an overlay multicast group address. A first portion of the underlay multicast group address is a function of the overlay multicast group address. The method further includes forwarding one or more multicast packets to one or more multicast receivers via the underlay multicast group using the underlay multicast group address.
