Creating a Multicast NAT Outbound Group

In multicast NAT, to translate an input multicast stream into output multicast streams, you must create a multicast NAT instance. If multiple input multicast streams need to be switched at the same time, create a multicast NAT instance group, add the multicast streams to the multicast NAT instance group, create a multicast NAT outbound group, add output multicast streams to the group, and then bind the multicast NAT outbound group to the multicast NAT instance group.
