Protocol Independent Multicast (PIM) register messages received from a downstream multicast Designated Routers (DR) must be filtered for any reserved or any other undesirable multicast groups.
Customer networks that do not maintain a multicast domain and only require the IP multicast service will be required to stand up a PIM-SM router that will be incorporated into the JIE shared tree s...Rule Low Severity -

Protocol Independent Multicast (PIM) join messages received from a downstream multicast Designated Routers (DR) must be filtered for any reserved or any other undesirable multicast groups.

Group -
Multicast register messages must be rate limited per each source-group (S, G) entry.
When a new source starts transmitting in a PIM Sparse Mode network, the DR will encapsulate the multicast packets into register messages and forward them to the Rendezvous Point (RP) using unicast....Rule Medium Severity -

Group -
Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) report messages must be filtered to allow hosts to join only those multicast groups that have been approved by the organization.
Real-time multicast traffic can entail multiple large flows of data. Large unicast flows tend to be fairly isolated (e.g., someone doing a file download here or there), whereas multicast can have b...Rule Low Severity -

Group -
Internet Group Management Protocol (IGMP) or Multicast Listener Discovery (MLD) snooping must be implemented within the network access layer.
The last-hop router sends the multicast packet out the interface towards the LAN containing interested receivers. The default behavior for a Layer 2 switch is to forward all multicast traffic out e...Rule Low Severity -

First-hop redundancy services must be configured to delay any preempt to provide enough time for the Internet Gateway Protocol (IGP) to stabilize.
The Layer 2 connection between the nodes providing first-hop redundancy comes up quickly. If the preemption takes effect prior to the routing protocol converging, traffic is black holed. Traffic wi...Rule Low 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.
