NAME

LLA_DAD_NAPostDAD_Reserved - NUT receives valide NA (Reserved Field)

TARGET

All Node

SYNOPSIS

LLA_DAD_NAPostDAD_Reserved.seq [-tooloption ...] -pkt <packetdef> [addrconf=<addrconfname>]

  -tooloption   : v6eval tool option
  <packetdef>   : packet definition file (v6eval tool option)
  <addrconfname>: how to configure address on NUT; boot/reboot

 detail of v6eval tool option: see perldoc V6evalTool.pm, perldoc V6evalRemote.pm

INITIALIZATION

 Reboot NUT or Initialize interface of NUT or Initialize IPv6 stack of NUT.

TEST PROCEDURE

Verify that a node can properly ignore invalid neighbor advertisements while performing Duplicate Address Detection.

   50. Initialize all devices on Link A.
   51. After TN1 receives a DAD NS message from the NUT, configure TN1 to transmit Neighbor Advertisement A with the Reserved 
       field set to 0x1FFFFFFF.
   52. Allow time for all devices on Link A to perform stateless address autoconfiguration and Duplicate Address Detection.
   53. Transmit a NS from TN1 to the solicited-node multicast address of the NUT's link-local address with the Target Address set to 
       the NUT's link-local address.
   54. Observe packet captures on Link A.
   55. Transmit a NS from TN1 to the link-local address of the NUT with the Target Address set to the NUT's link-local address.
   56. Observe packet captures on Link A.

JUDGEMENT

   Step 52: The NUT should ignore any options they do not recognize and continue processing the message.
            The NUT should not assign the tentative address to its interface.
   Step 54: The NUT must NOT transmit a Solicited NA for its autoconfigured link-local address.
   Step 56: The NUT must NOT transmit a Solicited NA for its autoconfigured link-local address.
