SRG-NET-000019-RTR-000005
Group -
The Cisco multicast edge router must be configured to establish boundaries for administratively scoped multicast traffic.
If multicast traffic is forwarded beyond the intended boundary, it is possible that it can be intercepted by unauthorized or unintended personnel. Administrative scoped multicast addresses are loc...Rule Low Severity -
SRG-NET-000362-RTR-000120
Group -
The Cisco multicast Rendezvous Point (RP) router must be configured to filter Protocol Independent Multicast (PIM) Join messages received from the Designated Router (DR) for any undesirable multicast groups.
MSDP peering between networks enables sharing of multicast source information. Enclaves with an existing multicast topology using PIM-SM can configure their RP routers to peer with MSDP routers. As...Rule Low Severity -
SRG-NET-000019-RTR-000013
Group -
The Cisco multicast Rendezvous Point (RP) router must be configured to filter Protocol Independent Multicast (PIM) Register messages received from the Designated Router (DR) for any undesirable multicast groups and sources.
Real-time multicast traffic can entail multiple large flows of data. An attacker can flood a network segment with multicast packets, over-using the available bandwidth and thereby creating a denial...Rule Low Severity -

SRG-NET-000362-RTR-000121
Group -
The Cisco multicast Rendezvous Point (RP) must be configured to rate limit the number of Protocol Independent Multicast (PIM) Register messages.
When a new source starts transmitting in a PIM Sparse Mode network, the Designated Router (DR) will encapsulate the multicast packets into register messages and forward them to the RP using unicast...Rule Medium Severity

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
