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 IGMPv3B.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 herC.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 1D.Multicast addresses 224.0.0.5 and 224.0.0.6 are source multicast addresses for OSPF routersE.The a dministratively scoped multicast addresses 239.0.0.0 through 239.255.255.255 are similar in purpose to RFC 1918 private unicast addressesF.Multicast address 224.0.1.1 has been reserved for the Network Time Protocol (NTP) by the IANA

In PIM-SM what control plane signaling must a multicast source perform before it begins to send multicasttraffic to a group？（）A、The source must send a PIM Register message to the rendezvous point （RP）.B、The source must first join the multicast group using IGMP before sending.C、The source must perform a Request to Send （RTS） and Clear to Send （CTS） handshake with the PIM designated router （DR）.D、No control plane signaling needs to be performed； the source can simply begin sending on the local subnet.
