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

  1. 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 option with the link-layer address of TR2.
  2. TR1 forwards an Echo Request from TN1 to the HUT. The IPv6 Source Address is the off-link
     global address of TN1. The IPv6 Destination Address is the global address of the HUT.
  3. Observe the packets transmitted by the HUT.


Observable Results

  Step 3:
  The HUT should respond to the Echo Request using TR2 as the first-hop, indicating the HUT
  processed the Redirect message and created a Destination Cache entry.


Possible Problems

  * None.
