The Cisco multicast switch must be configured to disable Protocol Independent Multicast (PIM) on all interfaces that are not required to support multicast routing.
<VulnDiscussion>If multicast traffic is forwarded beyond the intended boundary, it is possible that it can be intercepted by unauthorized or ...Rule Medium Severity -

The Cisco multicast switch must be configured to bind a Protocol Independent Multicast (PIM) neighbor filter to interfaces that have PIM enabled.
<VulnDiscussion>PIM is a routing protocol used to build multicast distribution trees for forwarding multicast traffic across the network infr...Rule Medium Severity -

<GroupDescription></GroupDescription>Group -
The Cisco multicast Rendezvous Point (RP) switch must be configured to limit the multicast forwarding cache so that its resources are not saturated by managing an overwhelming number of Protocol Independent Multicast (PIM) and Multicast Source Discovery Protocol (MSDP) source-active entries.
<VulnDiscussion>MSDP peering between networks enables sharing of multicast source information. Enclaves with an existing multicast topology u...Rule Low Severity -

The Cisco multicast Rendezvous Point (RP) switch must be configured to filter Protocol Independent Multicast (PIM) Register messages received from the Designated switch (DR) for any undesirable multicast groups and sources.
<VulnDiscussion>Real-time multicast traffic can entail multiple large flows of data. An attacker can flood a network segment with multicast p...Rule Low Severity -
