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.

Router Solicitation A

IPv6 Header Next Header: 58 Source Address: TN1's Link-local Address Destination Address: All Router multicast address

Router Advertisement Source Link-layer Option

Echo Request B

Neighbor Advertisement Router flag: 0 Solicited flag: 1 Override flag: 1

Procedure

  Part B: RS processing without SLL, no NCE
   4. TN1 transmits Router Solicitation A.
   5. TN1 transmits an Echo Request to the RUT.
   6. Check the NCE of TN1 on the RUT and observe the packets transmitted by the RUT.

Observable Results

  Part B
   Step 6:
   The RUT should create a Neighbor Cache Entry for TN1 and set the state of the
   Entry to INCOMPLETE. The RUT should send a multicast Neighbor Solicitation to TN1.
