NAME

LLA_DAD_NAPostDAD_wSLL - NUT receives valid NA (contains SLL)

TARGET

All Node

SYNOPSIS

LLA_DAD_NAPostDAD_wSLL.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.

   63. Initialize the devices on Link A.
   64. After TN1 receives a DAD NS message from the NUT, configure TN1 to transmit Neighbor Advertisement A containing 
       a SLL Option set to TN1's MAC address.
   65. Allow time for all devices on Link A to perform stateless address autoconfiguration and Duplicate Address Detection.
   66. 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.
   67. Observe packet captures on Link A.
   68. 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.
   69. Observe packet captures on Link A.

JUDGEMENT

   Step 65: 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 67: The NUT must NOT transmit a Solicited NA for its autoconfigured link-local address.
   Step 69: The NUT must NOT transmit a Solicited NA for its autoconfigured link-local address.
