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.

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

• A、Multicast addresses 224.0.0.13 and 224.0.0.22 are reserved link - local addresses used by PIMv2 and IGMPv3
• B、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 toget her
• C、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
• D、Multicast addresses 224.0.0.5 and 224.0.0.6 are source multicast addresses for OSPF routers
• E、The a dministratively scoped multicast addresses 239.0.0.0 through 239.255.255.255 are similar in purpose to RFC 1918 private unicast addresses
• F、Multicast address 224.0.1.1 has been reserved for the Network Time Protocol (NTP) by the IANA
