How do "routers" handle packet fragmentation in IPv6?

		Each router in the path sends probe packets to determine smallest MTU along the remaining path to determine how to fragment the packet.
		Router divides packet into smaller fragments that are not larger than the MTU on the next link and the Identification field is used to group the fragments back together by the next router.
		Routers do not fragment the packets, they return an error to the sender.
		Host sets up fragmented packets, identifies the fragments by identification number and source IP and the fragments are reassembled by the final router in the path.
