This phase triggers section 11.2 of the Policy Manual, under which a /10 block is reserved for gradual exhaustion. To block or unblock IPv4 multicast packets, use the SETSOCKOPT API and specify the IP_MREQ_SOURCE structure containing IPv4 multicast address, IPv4 source address, and the local IPv4 interface address. The format of the IP_MREQ_SOURCE structure is in the BPXYSOCK macro.
