发布日期:2021-11-25

Which three IP multicast address related statement...
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.
