solicited-node multicast address?
A.
FF01::1:200E:88AA
B.
FF01::1:FF0E:88AA
C.
FF01:0DB8::1:800:200E:88AA
D.
FF02::1:FF0E:88AA
E.
FF02::1:200E:88AA
F.
FF02:0DB8::1:800:200E:88AA
Explanation:
IPv6 nodes (hosts and routers) are required to join (receive packets destined for) the
following multicast groups:
•All-nodes multicast group FF02:0:0:0:0:0:0:1 (scope is link-local)
•Solicited-node multicast group FF02:0:0:0:0:1:FF00:0000/104 for each of its assigned
unicast and anycast addresses
IPv6 routers must also join the all-routers multicast group FF02:0:0:0:0:0:0:2 (scope is linklocal).
The solicited-node multicast address is a multicast group that corresponds to an IPv6 unicast
or anycast address. IPv6 nodes must join the associated solicited-node multicast group for
every unicast and anycast address to which it is assigned. The IPv6 solicited-node multicast
address has the prefix FF02:0:0:0:0:1:
FF00:0000/104 concatenated with the 24 low-order bits of a corresponding IPv6 unicast or
anycast address (see Figure 2). For example, the solicited-node multicast address
corresponding to the IPv6 address 2037::01:800:200E:8C6C is FF02::1:FF0E:8C6C.
Solicited-node addresses are used in neighbor solicitation messages
