The multicast domain must block inbound and outbound administratively-scoped multicast traffic at the edge.
An XCCDF Rule
Description
A multicast boundary must be established to ensure that administratively-scoped multicast traffic does not flow into or out of the IP core. The multicast boundary can be created by ensuring that COI-facing interfaces on all PIM routers are configured to block inbound and outbound administratively-scoped multicast traffic.
