  • 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.

    &lt;VulnDiscussion&gt;Real-time multicast traffic can entail multiple large flows of data. Large unicast flows tend to be fairly isolated (i.e., so...

    Group
  • The Cisco multicast Designated switch (DR) must be configured to set the shortest-path tree (SPT) threshold to infinity to minimalize source-group (S, G) state within the multicast topology where Any Source Multicast (ASM) is deployed.

    &lt;VulnDiscussion&gt;ASM can have many sources for the same groups (many-to-many). For many receivers, the path via the RP may not be ideal compar...

  • The Cisco Multicast Source Discovery Protocol (MSDP) switch must be configured to only accept MSDP packets from known MSDP peers.

    &lt;VulnDiscussion&gt;MSDP peering with customer network switches presents additional risks to the DISN Core, whether from a rogue or misconfigured...
