- 10. 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

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: Packets addressed to a unicast address are delivered to a single interface.
Explanation:
Packets addressed to a unicast address are delivered to a single interface. For load balancing, multiple interfaces can use the same address.
Correct Answer: Router1(config-if)# ipv6 router rip 1
Explanation:
It'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.
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.
