Information

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

GROUP ID: V-221143
RULE ID: SV-221143r999752

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.

Solution

Configure the switch to authenticate MSDP messages as shown in the following example:

SW1(config)# ip msdp password x.1.28.2 xxxxxxxxxxxx
