Information

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

GROUP ID: V-216819RULE ID: SV-216819r856456

MSDP peering with customer network routers presents additional risks to the core, whether from a rogue or misconfigured MSDP-enabled router.

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 router to authenticate MSDP messages as shown in the following example:

RP/0/0/CPU0:R2(config)#router msdpRP/0/0/CPU0:R2(config-msdp)#peer x.14.2.1RP/0/0/CPU0:R2(config-msdp-peer)#password clear xxxxxxxxxxxxRP/0/0/CPU0:R2(config-msdp-peer)#exitRP/0/0/CPU0:R2(config-msdp)#peer x.15.3.5RP/0/0/CPU0:R2(config-msdp-peer)#password clear xxxxxxxxxxxRP/0/0/CPU0:R2(config-msdp-peer)#end
