NAME

  Test v6LC.2.1.16 - Neighbor Advertisement Processing, No NCE
  Part A: Receiving NA with S = 0, O = 0, and TLLA

Purpose

  Verify that a node silently discards a Neighbor Advertisement if the target does not have a
  Neighbor Cache entry.

References

  * [ND]  Section 7.2.5

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.

Neighbor Advertisement A

IPv6 Header Next Header: 58

Neighbor Advertisement Solicited flag: 0 Override flag: 0 Target Link-layer Option

Neighbor Advertisement B

IPv6 Header Next Header: 58

Neighbor Advertisement Solicited flag: 0 Override flag: 1 Target Link-layer Option

Neighbor Advertisement C

IPv6 Header Next Header: 58

Neighbor Advertisement Solicited flag: 1 Override flag: 0 Target Link-layer Option

Neighbor Advertisement D

IPv6 Header Next Header: 58

Neighbor Advertisement Solicited flag: 1 Override flag: 1 Target Link-layer Option

Procedure

  Part A: Receiving NA with S = 0, O = 0, and TLLA
   1. TN1 transmits Neighbor Advertisement A.
   2. Observe the packets transmitted by the NUT and the NC on the NUT.
   3. TN1 transmits an Echo Request to the NUT.
   4. Observe the packets transmitted by the NUT and the NC on the NUT.

Observable Results

  Parts A-H
   For each part, after receiving the Neighbor Advertisement from TN1, the NUT should not
   transmit any packets and no NCE's should be created for TN1. After receiving the Echo
   Request from TN1, the NUT should create a Neighbor Cache Entry for TN1 and set the state
   of the Entry to INCOMPLETE. The NUT should send a multicast Neighbor Solicitation to
   TN1.

Possible Problems

  * None.
