What two multicast addresses does OSPFv3 use?
1.FF02::A
2.FF02::9
3.FF02::5
4.FF02::6
Answer: D
Adjacencies and next-hop attributes now use link-local addresses, and OSPFv3 still uses multicast traffic to send its updates and acknowledgments with the addresses FF02::5 for OSPF routers and FF02::6 for OSPF designated routers. These are the replacements for 224.0.0.5 and 224.0.0.6, respectively.
