NAME

LLA_DAD_NSPostDAD_wTLL - NUT receives valid DAD NS (contains TTL)

TARGET

All Node

SYNOPSIS

LLA_DAD_NSPostDAD_wTLL.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 taht a node can properly ignore invalid neigbor solicitations while performing Duplicate Address Detection.

   70. Initialize the devices on Link A.
   71. After TN1 receives a DAD NS message from the NUT, configure TN1 to transmit Neighbor Solicitation A 
       containing a TLL Option set to TN1's MAC address.
   72. Allow time for all devices on Link A to perform stateless address autoconfiguration and Duplicate Address 
       Detection.
   73. 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.
   74. Observe packet captures on Link A.
   75. 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.
   76. Observe packet captures on Link A.

JUDGEMENT

   Step 72: The NUT should ignore the contents of the Reserved field.
            The NUT should not assign the tentative address to its interface.
   Step 74: The NUT must NOT transmit a Solicited NA for its autoconfigured link-local address.
   Step 76: The NUT must NOT transmit a Solicited NA for its autoconfigured link-local address.
