Resource Requirements

  * Packet generator
  * Monitor to capture packets

Test Setup

  No Common Test Setup is performed. 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.

Procedure

  1. TR1 transmits Router Advertisement A.
  2. TR1 transmits Packet A. TR1 should not respond to Neighbor Solicitations from the HUT.
  3. Observe the packets transmitted by the HUT.
  4. TR1 transmits Router Advertisement A with the on-link (L) flag clear.
  5. TR1 transmits Packet A. TR1 should not respond to Neighbor Solicitations from the HUT.
  6. Observe the packets transmitted by the HUT.

Observable Results

  Step 3: 
  In response to Packet A, the HUT should transmit 3 Neighbor Solicitations with a Target
  Address of TR1's global address.

  Step 6: 
  In response to Packet A, the HUT should transmit 3 Neighbor Solicitations with a Target
  Address of TR1's global address.

Possible Problems

  * None.
