#CCENT and #CCNA Fast Start: an IPv6 Address Question

You take a new #CCENT or #CCNA practice exam, and see a few questions about IPv6 addresses. You focused on the basic format – how to abbreviate, how to expand, and what the prefix length means. Then the practice exam asks you something about which address is in which category, or what it’s used for normally, and all you see is the hexadecimal address – so you draw a blank. Today’s post poses an ICND1 level IPv6 addressing question that makes you think about the usage of an IPv6 address, based on the address value itself, taking the discussion a bit beyond just how to decipher the numbers.

The Question

(Wendell’s note to self: internal question number 112.)

Host A, in a bank branch office in Atlanta, Ga., is able to send IPv6 packets back and forth with server S1 in Charlotte, NC. The routers use OSPFv3. Which of the following address(es) could be used as the next-hop IPv6 address of the route, learned with OSPFv3, that router R1 uses to forward an IPv6 packet from host A to server S1?

A) 3456:1234:5678:9AB:1111:2222:3333:4444

B) FE80::200:FF:FE00:1111

C) FD00:DEAD:BEEF:CAFE:101:20:3:1111

D) FF02::1:FF00:1234

E) ::

F) FF02::5

(Note that unlike the real Cisco exams, this sample question does NOT identify the number of correct answers, just to add to the challenge level.)

    This was a bit of a doozy, OSPFv3 is mentioned in Ch28 of your ICND1 book but I can’t find where it talks about anything other than it using v3 instead of v2.
