JUEX-RT-000570 - The Juniper Multicast Source Discovery Protocol (MSDP) router must be configured to authenticate all received MSDP packets.
Information
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
Ensure all MSDP packets received by an MSDP router are authenticated.set protocols msdp active-source-limit maximum <1..1000000>
set protocols msdp active-source-limit threshold <1..1000000>
set protocols msdp active-source-limit log-warning <percent to log warning>
<additional configuration>
set protocols msdp peer <address> authentication-key <PSK>
