Assessment Title
Rule Text
The multicast Rendezvous Point (RP) Arista router must be configured to filter Protocol Independent Multicast (PIM) Register and Join messages received from the Designated Router (DR) for any undesirable multicast groups and sources.
Description
Discussion Text
Real-time multicast traffic can entail multiple large flows of data. An attacker can flood a network segment with multicast packets, over-using the available bandwidth and thereby creating a denial-of-service (DoS) condition. Hence, it is imperative that register messages are accepted only for authorized multicast groups and sources.
