The Cisco multicast edge switch 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 lo...Rule Low Severity -

The Cisco multicast Designated switch (DR) must be configured to filter the Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) Report messages to allow hosts to join only 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 (i.e., someone doing a file download here or there), whereas multicast can have b...Rule Low Severity -

The Cisco switch must not be configured to use IPv6 Site Local Unicast addresses.
As currently defined, site local addresses are ambiguous and can be present in multiple sites. The address itself does not contain any indication of the site to which it belongs. The use of site-lo...Rule Medium Severity -

The Cisco perimeter switch must be configured to suppress Router Advertisements on all external IPv6-enabled interfaces.
Many of the known attacks in stateless autoconfiguration are defined in RFC 3756 were present in IPv4 ARP attacks. To mitigate these vulnerabilities, links that have no hosts connected such as the ...Rule Medium Severity -

The Cisco perimeter switch must be configured to drop IPv6 undetermined transport packets.
One of the fragmentation weaknesses known in IPv6 is the undetermined transport packet. This packet contains an undetermined protocol due to fragmentation. Depending on the length of the IPv6 exten...Rule Medium Severity
