The NSX Tier-0 Gateway router must be configured to disable Protocol Independent Multicast (PIM) on all interfaces that are not required to support multicast routing.
If multicast traffic is forwarded beyond the intended boundary, it could be intercepted by unauthorized or unintended personnel. Limiting where within the network a given multicast group's data is ...Rule High Severity -
