Which three IP multicast address related statements are true？ （Choose three.） （） 

• A、Multicast addresses 224.0.0.0 through 224.0.0.255 are always forwarded because they are transmitted  with Time to Live （TTL） greater than 1.
• B、Multicast addresses 224.0.0.5 and 224.0.0.6 are source multicast addresses for OSPF routers.
• C、Multicast addresses 224.0.0.13 and 224.0.0.22 are reserved link-local addresses used by PIMv2 and  IGMPv3.
• D、Because they would map to overlapping IP multicast MAC addresses， multicast addresses 224.0.1.1  and 238.1.1.1 could not be used together.
• E、Multicast address 224.0.1.1 has been reserved for the Network Time Protocol （NTP） by the IANA
• F、The administratively scoped multicast addresses 239.0.0.0 through 239.255.255.255 are similar in  purpose to RFC 1918 private unicast addresses.
