  Part A: Send Redirect

Purpose

   Verify that a router properly handles transmission of Redirect messages.

  * [ND]  Sections 8.2

Resource Requirements

  * Packet generator
  * Monitor to capture packets

Test Setup

  Common Setup 1.1 is performed at the beginning of each test part. The Common Test
  Cleanup Procedure is performed after each part.

                    i. TN2 is an on-link neighbor on Link B to TN1 (instead of residing on Link A
                       depicted in Common Topology).
                   ii. RUT advertises prefix X on Link B.

Procedure

  Part A: Send Redirect
   1. TN1 transmits an Echo Request to TN2's unicast global address with prefix X and a first hop
      through the RUT.
   2. Observe the packets transmitted by the RUT.

Observable Results

  Part A
   Step 2: The RUT should transmit a Redirect message with the following values:
       IPv6 Source             Link-Local address of RUT
       IPv6 Destination        TN1's address (used in Echo Request's Source Address)
       IPv6 Hop Limit          255
       Target                  TN2's unicast global address with prefix X
       Destination             TN2's unicast global address with prefix X
       TLL Option              TN2's link-layer address if known
       Redirected Header       TN1's Echo Request without total packet exceeding 1280
                               bytes.

Possible Problems

  * The RUT may not support the generation of Redirect messages.
