Ch 15 Review Q6 anycast

[lammle]

Anycast is defined as one-to-many.
However, with that said, the bottom line is that a single packet will be delivered to only one to device.
With anycast, many servers, as an example, will have the same IPv6 unicast address. Routers will load balance on a link to these servers and deliver the packet to the nearest anycast address, but they won't deliver the packet to more than one device. The next packet might go to a different device, or the same, depending on the routers.
This is basically a very cool load-balancing technique built inside IPv6.
Hope this helps.
