A.
OSPFv3 uses global IPv6 addresses to establish neighbor adjacencies.

B.
RT1 has a subnet mask of 64 bits.

C.
RT1 has FastEthernet0/0 set as a DR for network type broadcast.

D.
OSPFv3 uses Link-local addresses to establish neighbor adjacencies.

E.
RT1 does not have a global IPv6 address set on FastEthernet0/0.

F.
OSPFv3 uses IPv4 addresses to establish neighbor adjacencies.

Explanation:
As shown information, we notice that the router with both ipv6 address and ipv4 address and both of them are
in ospf process, so in OSPFv3, we can find that, the DR BDR address are all link local address, so in OSPFv3 it
establish neighboor with link local address
