=head1 Title

  Test v6LC.2.3.15: Invalid Redirect does not Update Neighbor Cache (Hosts Only)
  Part I: Option has Length Zero

=head1 Purpose

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

=head1 References

  * [ND]  Sections 8.1

=head1 Resource Requirements

  * Packet generator
  * Monitor to capture packets

=head1 Test Setup

  Common Setup 1.1 is performed at the beginning of each test part. Wait at least 3
  seconds (MAX_MULTICAST_SOLICIT * RETRANS_TIMER) after any previous cleanup to make sure
  all previous NCE's are in state No NCE. The Common Test Cleanup Procedure is performed after each
  part.

=head1 Procedure

  Part I: Option has Length Zero
   15. Repeat Steps 1 through 7 from Part A. In Step 1, the Redirect message contains an Option with
       length 0.

=head1 Observable Results

  Parts A through I
   Step 2:
   The HUT should respond to the Echo Request using TR1 as a first hop.

   Step 7:
   The HUT should transmit a multicast Neighbor Solicitation for TR2, indicating the
   HUT did not create a NCE for TR2 upon reception of an invalid Redirect message.

=head1 Possible Problems

  * None.
