The Cisco Multicast Source Discovery Protocol (MSDP) switch must be configured to use a loopback address as the source address when originating MSDP traffic.
The Cisco Multicast Source Discovery Protocol (MSDP) switch must be configured to use a loopback address as the source address when originating MSDP traffic. An XCCDF Rule
The Cisco Multicast Source Discovery Protocol (MSDP) switch must be configured to use a loopback address as the source address when originating MSDP traffic.
Low Severity
<VulnDiscussion>Using a loopback address as the source address offers a multitude of uses for security, access, management, and scalability of MSDP switches. It is easier to construct appropriate ingress filters for switch management plane traffic destined to the network management subnet since the source addresses will be from the range used for loopback interfaces instead of a larger range of addresses used for physical interfaces. Log information recorded by authentication and syslog servers will record the switch’s loopback address instead of the numerous physical interface addresses.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
