The Cisco Multicast Source Discovery Protocol (MSDP) switch must be configured to authenticate all received MSDP packets.

Description

<VulnDiscussion>MSDP peering with customer network switches presents additional risks to the core, whether from a rogue or misconfigured MSDP-enabled switch. MSDP password authentication is used to validate each segment sent on the TCP connection between MSDP peers, protecting the MSDP session against the threat of spoofed packets being injected into the TCP connection stream.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
