8)The server issues a Specific Route TEST frame (also called a non-broadcast frame) in response using the route indicated in the ARE TEST frame. Note that the server does not have to broadcast (use ARE) to get the TEST response back to the PC; it uses a Specifically Routed TEST frame (Figure 26).

9)The response TEST frame also has a Routing Information Field (RIF) with the same path trace as the original ARE TEST frame except the Direction bit is set to 1. This reverses the direction in which the RIF sequence is read and indicates the path back to the source. The RIF also sets three bits in the Routing Type field that indicate the frame is to be specifically routed and not broadcast.

10)When the response TEST frame reaches the source PC, the PC now knows what route to use to send its frames to the server.
