  Advertisement.

References

  * [ND]  Sections 6.3.4 and 7.3.3

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 after each
  part.

Procedure

  Part A: RA processing, no NCE
   1. TR1 transmits Router Advertisement A.
   2. TR1 transmits an Echo Request to the HUT.
   3. Check the NCE of TR1 on the HUT and observe the packets transmitted by the HUT.

Observable Results

  Part A
   Step 3:
   The HUT must create a NCE for TR1, set the NCE's state to STALE, and record
   TR1's Link-layer Address. Because the HUT's NCE for TR1 is in state STALE, the HUT
   should send an Echo Reply to TR1 and enter state DELAY. After
   DELAY_FIRST_PROBE_TIME, the HUT should send a unicast Neighbor Solicitation to
   TR1.

Possible Problems

  * None.
