Resource Requirements

  * Packet generator
  * Monitor to capture packets

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. The following table details the Redirect message transmitted in each Part:

TLLA Option	Redirected Packet Option	New NC State	Link-layer Address	Part
Yes	Yes	STALE	Updated	C

Procedure

  Part C: TLLA Option, Redirected Packet Option, Link-layer Address Updated
   14. Repeat Steps 6 through 9 from Part B, using the Redirect message detailed in the table above.

Observable Results

  Parts B through D
   Step 9:
   The HUT should respond to the Echo Request using TR1 as a first hop.

   Step 11:
   The HUT should send a multicast Neighbor Solicitation for TR2, indicating the
   HUT has an NCE for TR2 in state INCOMPLETE.

   Step 13:
   Because the HUT's NCE for TR2 is in state STALE, the HUT should send an Echo
   Reply to TR2 using the new Link-Layer address and enter state DELAY. After
   DELAY_FIRST_PROBE_TIME, the HUT should send a unicast Neighbor Solicitation to
   TR2.

Possible Problems

  * None.
