Some embodiments provide a system that determines an internal multicast group identifier based on a source address, a multicast address, and a multicast tree identifier field associated with a multicast packet. The system can then forward the multicast packet based on the internal multicast group identifier. Specifically, the system can determine a first set of bits based on the source address and the multicast address of the multicast packet. The system can determine a second set of bits based on the multicast tree identifier field of the multicast packet. Next, the system can combine the first set of bits and the second set of bits to obtain the internal multicast group identifier. In some embodiments, the scope of an internal virtual network identifier does not extend beyond a switch or a forwarding module within a switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Supporting multiple multicast trees in trill networks","description":"Systems and techniques for supporting multiple multicast trees are described.
