The Arista Multilayer Switch must establish boundaries for IPv6 Admin-Local, IPv6 Site-Local, IPv6 Organization-Local scope, and IPv4 Local-Scope multicast traffic.
The Arista Multilayer Switch must establish boundaries for IPv6 Admin-Local, IPv6 Site-Local, IPv6 Organization-Local scope, and IPv4 Local-Scope multicast traffic. An XCCDF Rule
The Arista Multilayer Switch must establish boundaries for IPv6 Admin-Local, IPv6 Site-Local, IPv6 Organization-Local scope, and IPv4 Local-Scope multicast traffic.
Medium Severity
<VulnDiscussion>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 locally assigned and are to be used exclusively by the enterprise network or enclave. Administrative scoped multicast traffic must not cross the enclave perimeter in either direction. Restricting multicast traffic makes it more difficult for a malicious user to access sensitive traffic.
Admin-Local scope is encouraged for any multicast traffic within a network intended for network management, as well as for control plane traffic that must reach beyond link-local destinations.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
