Purpose

   Verify that a host properly processes invalid Redirect messages when redirected on-link.

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 A: Redirect Source Address is Global
   1. TR1 forwards an Echo Request from TN1 to the HUT. The Source Address is the off-link global
      address of TN1. The Destination Address is the global address of the HUT.
   2. Observe the packets transmitted by the HUT.
   3. 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 an incorrect IPv6 Source Address (the off-link global address of TN2).
   4. TR1 forwards an Echo Request from TN1 to the HUT. The Source Address is the off-link global
      address of TN1. The Destination Address is the global address of the HUT.
   5. Observe the packets transmitted by the HUT.


Observable Results

  Parts A-I
   In all Parts, the HUT should respond to the first Echo Request using TR1 as a first hop. The
   HUT should also respond to the second Echo Request using TR1 as a first hop, indicating the
   HUT did not process the invalid Redirect message.


Possible Problems

  * None.
