Claim:
1. A switch, comprising: determining circuitry configured to determine, for a first multicast packet, a first internal multicast group identifier comprising a first and a second sets of bits, and for a second multicast packet, a second internal multicast group identifier comprising the first and a third sets of bits, wherein the first set of bits is determined based on a multicast-address and a source address of the first multicast packet, wherein the second set of bits is determined based on a first multicast tree identifier, which is a switch identifier of a root switch of a first multicast tree corresponding to a first virtual network, and wherein the third set of bits is determined based on a second multicast tree identifier, which is a switch identifier of a root switch of a second multicast tree corresponding to a second virtual network; forwarding circuitry configured to:
