Resource Requirements

  * Packet generator
  * Monitor to capture packets


Test Setup

  The following setup procedure is performed before each Part:
      a) Perform Common Setup 1.1.
      b) TR2 transmits an Echo Request to the HUT's link-local address. TR2 responds to any
         Neighbor Solicitations from the HUT with a Neighbor Advertisement with the solicited bit set to
         1 causing the HUT to update it's NCE for TR2 to sate REACHABLE.
  The Common Test Cleanup Procedure is performed after each part.


Procedure

  Part B: Reserved Field is Non-zero
   6. TR1 forwards an Echo Request to the HUT. The Source Address is the off-link global address of
      TN1. The Destination Address is the global address of the HUT.
   7. Observe the packets transmitted by the HUT.
   8. TR1 transmits a Redirect message to the HUT. The ICMPv6 Destination Address is the global
      address of TN1. The Target Address is the link-local address of TR2. The Redirect message
      contains a Target Link-layer Address option. The Redirect message also contains a non-zero
      Reserved field.
   9. TR1 forwards an Echo Request to the HUT. The Source Address is the off-link global address of
      TN1. The Destination Address is the global address of the HUT.
  10. Observe the packets transmitted by the HUT.


Observable Results

  Parts A-B
   In all Parts, the HUT should respond to the first Echo Request using TR1 as a first hop. The
   HUT should respond to the second Echo Request using TR2 as a first hop, indicating the
   HUT processed the Redirect message.


Possible Problems

  * None.
