To enable RIPng, which of the following would you use?
Options- A. Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
- B. Router1(config-if)# ipv6 router rip 1
- C. Router1(config)# ipv6 router eigrp 10
- D. Router1(config-rtr)# no shutdown
- E. Router1(config-if)# ipv6 eigrp 10
- Correct Answer
- Router1(config-if)# ipv6 router rip 1
ExplanationIt's pretty simple to enable RIPng for IPv6. You configure it right on the interface where you want RIP to run with the ipv6 router rip number command. - 1. Which statement(s) about IPv4 and IPv6 addresses are true?
- An IPv6 address is 32 bits long, represented in hexidecimal.
- An IPv6 address is 128 bits long, represented in decimal.
- An IPv4 address is 32 bits long, represented in decimal.
- An IPv6 address is 128 bits long, represented in hexidecimal.
Options- A. 1 and 3 only
- B. 2 only
- C. 3 and 4
- D. 2 and 4 Discuss
- 2. Which of the following is true when describing a unique local address?
Options- A. Packets addressed to a unicast address are delivered to a single interface.
- B. These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.
- C. These are like private addresses in IPv4 in that they are not meant to be routed.
- D. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap. Discuss

Options- A. FF02::A
- B. FF02::9
- C. FF02::5

- Router1(config-if)# ipv6 eigrp 10
Options- A. 1, 3 and 5
- B. 3, 4 and 5
- C. 1 and 3
- D. 5 only Discuss
- 6. Which of the following is true when describing a global unicast address?

- B. These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.
- C. These are like private addresses in IPv4 in that they are not meant to be routed.
- D. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap. Discuss
- 7. To enable OSPFv3, which of the following would you use?
Options- A. Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
- B. Router1(config-if)# ipv6 router rip 1
- C. Router1(config)# ipv6 router eigrp 10
- D. Router1(config-rtr)# no shutdown
- E. Router1(config-if)# ipv6 eigrp 10 Discuss

- FF02::A
- FF02::9
- FF02::5
- FF02::6
Options- A. 2 only
- B. 3 only
- C. 1 and 3
- D. 3 and 4 Discuss
- 9. Which of the following is true when describing a multicast address?
Options- A. Packets addressed to a unicast address are delivered to a single interface.
- B. Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address.
- C. Identifies multiple interfaces and is only delivered to one address. This address can also be called one-to-one-of-many.
- D. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap. Discuss
- 10. You want to ping the loopback address of your local host(with IPv6). What will you type?

Correct Answer: 3 and 4
Explanation:
IPv4 addresses are 32 bits long and are represented in decimal format. IPv6 addresses are 128 bits long and represented in hexadecimal format.
Correct Answer: These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
Explanation:
These addresses are meant for nonrouting purposes like link-local, but they are almost globally unique so it is unlikely they will have an address overlap. Unique local addresses were designed as a replacement for site-local addresses.
Correct Answer: FF02::9
Explanation:
RIPng uses the multicast IPv6 address of
FF02::9. If you remember the multicast addresses for IPv4, the numbers at the end of each IPv6 address are the same.
Correct Answer: FF02::A
Explanation:
EIGRPv6's multicast address stayed very near the same. In IPv4 it was
224.0.0.10; now it is
FF02::A (A=10 in hexadecimal notation).
Correct Answer: 3, 4 and 5
Explanation:
Unlike RIPng and OSPFv3, you need to configure EIGRP both from global configuration mode and from interface mode, and you have to enable the command with the
no shutdown command.
Correct Answer: These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.
Explanation:
Unlike unicast addresses, global unicast addresses are meant to be routed.
Correct Answer: Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
Explanation:
To enable OSPFv3, you enable the protocol as with RIPng. The command string is ipv6
ospf <process-id> area <area-id>.
Correct Answer: 3 and 4
Explanation:
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.
Correct Answer: Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address.
Explanation:
Packets addressed to a multicast address are delivered to all interfaces identified by the multicast address, the same as in IPv4. It is also called a one-to-many address. You can always tell a multicast address in IPv6 because multicast addresses always start with
FF.
Correct Answer: ping ::1
Explanation:
The loopback address with IPv4 is
127.0.0.1. With IPv6, that address is
::1.
