Which three are characteristics of an IPv6 anycast address? (Choose three)
Click on the arrows to vote for the correct answerA. B. C. D. E. F.
An IPv6 anycast address is an address assigned to a group of devices, but packets sent to the anycast address are delivered only to the nearest (in terms of routing distance) device in the group. An anycast address is used when one or more devices in a group can provide the same service, and the sender only needs to reach one of them.
The three characteristics of an IPv6 anycast address are:
B. Delivery of packets to the group interface that is closest to the sending device: When packets are sent to an anycast address, they are delivered to the network interface of the nearest device in the group, based on the routing distance between the sender and the devices in the group. This allows for more efficient routing of packets, as they are only delivered to the nearest device that can provide the service.
E. The same address for multiple devices in the group: An anycast address is the same for all devices in the group, which allows them to share the same IP address. This is different from a unicast address, which is unique to each device.
F. One-to-nearest communication model: An anycast address allows for one-to-nearest communication, as packets are delivered only to the nearest device in the group. This is different from a multicast address, which allows for one-to-many communication.
Therefore, the correct answers are B, E, and F.
A is incorrect because anycast does not use one-to-many communication.
C is incorrect because any-to-many communication is not a characteristic of anycast addresses.
D is incorrect because anycast addresses are the same for all devices in the group, and do not have unique addresses for each device.
