By using Source-Specific Multicast, you eliminate the need for RPs and prevent unauthorized sources from injecting traffic into the VPN’s multicast trees. Assigning your MDT control and data groups into the SSM range ensures only the trusted training server’s IPv4 addresses can be subscribed to, meeting the high-security requirement.
