Which address needs to be present on an interface for OSPFv3 to form an adjacency?

A.
Global unicast

B.
Unique local

C.
Link local

D.
FF02::5

E.
FF02::6

Explanation:
OSPFv3, however, makes use of IPv6’s link-local address scope (FE80::/10). All OSPFv3
adjacencies are formed using link-local addresses:
R1# show ipv6 ospf neighbor detail

Neighbor 3.3.3.3
In the area 1 via interface FastEthernet0/0
Neighbor: interface-id 4, link-local address FE80::C003:7DFF:FE07:0
Neighbor priority is 1, State is FULL, 6 state changes
DR is 3.3.3.3 BDR is 2.2.2.2
Options is 0x6670B96D
Dead timer due in 00:00:32
Neighbor is up for 00:16:48
Index 1/1/1, retransmission queue length 0, number of retransmission 0
First 0x0(0)/0x0(0)/0x0(0) Next 0x0(0)/0x0(0)/0x0(0)
Last retransmission scan length is 0, maximum is 0
Last retransmission scan time is 0 msec, maximum is 0 msec
