The device extracts information relating to a multicast packet encapsulated within the unicast packet when the unicast packet is a Data Register message, and performs a security policy lookup based on the extracted multicast packet information to identify a security policy associated with the multicast packet. The device determines whether the identified security policy authorizes forwarding of the unicast packet, and establishes a multicast data session when the identified security policy authorizes forwarding of the unicast packet. The device establishes a multicast control session based on the multicast data session, where the multicast control session authorizes transmission of PIM-related control messages associated with the multicast packet. The device forwards the unicast packet to the unicast destination based on the multicast data session."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Policy handling for multicast transmissions","description":"A device, receives a unicast packet designating a unicast source and a unicast destination, and determines whether the received unicast packet is a Data Register message.
