1. A method comprising:
operating a first switch as a part of a virtual switch in conjunction with a second switch, and wherein the virtual switch is to operate as a gateway for an overlay tunnel fabric that includes the first and second switches;
operating, at the first switch, a rendezvous point (RP) for a multicast group;
determining, by the first switch, whether to synchronize a registration packet associated with the multicast group with the second switch based on a type of a first ingress connection via which the registration packet is received at the first switch;
in response to the type of the first ingress connection indicating an overlay tunnel, synchronizing the registration packet with the second switch; and
determining whether to receive subsequent registration packets for the multicast group based on the type of the first ingress connection and reception of a join request for the multicast group from a host, wherein a type of a respective connection indicates whether the connection includes an overlay tunnel of the overlay tunnel fabric.
