Anycast is a very different beast, though. Anycast is just unicast but you announce the same IP space from multiple destinations, and the network figures out how to get a packet to the closest one. If one of those destinations fails, it just goes to the next closest one. Unicasts, multicasts, and broadcasts all actually work differently underneath and require specific handling by network equipment. Anycast is just a special case of unicast and generally speaking network equipment is completely unaware of it.
