=head1 Title

  Test v6LC.2.3.6: Redirected to Alternate Router: Invalid (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 4.5 and 8.1
  * [ICMPv6]  Section 2.4

=head1 Resource Requirements

  * Packet generator
  * Monitor to capture packets

=head1 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.

=head1 Procedure

  Part I: Option has Length Zero
   13. Repeat Steps 1 through 5 from Part A. In Step 4, the Redirect message contains an Option with
       length 0.

=head1 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.

=head1 Possible Problems

  * None.
