=head1 Title

  Test v6LC.2.2.19: Router Advertisement Processing, On-link determination (Hosts Only)

=head1 Purpose

  Verify that a host properly rejects an invalid prefix length, however the prefix length is still
  valid for on-link determination when the on-link flag is true.

=head1 References

  * [ND]  Section 6.3.4
  * [ADDRCONF]  Section 5.5.3

=head1 Resource Requirements

  * Packet generator
  * Monitor to capture packets

=head1 Test Setup

  Refer to Common Test Setup 1.1. The Common Test Cleanup procedure is performed
  after each part.

=head1 Procedure

  1. TR1 transmits Router Advertisement A to the HUT.
  2. TN1 transmits Echo Request B to the HUT.
  3. Observe the packets transmitted by the HUT.

=head1 Observable Results

  Step 3:
  The HUT should transmit an Echo Reply to TN1's global address on-link.
=head1 Possible Problems

  * None.
