Network Requirements

IGMPv3 is Required on your Network for redundancy. New MTD multicasts require IGMPv3 to be enabled on the router ports connected to the MTD Servers. IGMPv3 enables SSM or Source Specific Multicast traffic which allows MTD server 01 and 02 to both output the same multicast for redundancy.
