NAME

sendMcastNS2 - Verify that NUT sends multicast NS by the configured rules

TARGET

Host and Router

Host only

SYNOPSIS

  sendMcastNS2.seq [-tooloption ...] -p sendMcastNS2.def

INITIALIZATION

A CASE OF A HOST

Send RA with RetransTimer=3sec to initiate NUT's retrans time.
Clear NC state for TN.

  TN                   NUT
  ------------------------
  ==== unsolicited RA ===>
        src=X's link-local
        dst=all-node
        M=0, O=0
        Lifetime=600, ReachableTime=0, RetransTimer=3000

A CASE OF A ROUTER

  Clear NC state for TN.

TEST PROCEDURE

sendMcastNS verifies NUT send multicast NSs by the rules that are configured by a RA(in host cast) or manual (in router cast).

  TN                           NUT
  --------------------------------


  State: NONCE (for TN)


  ==== echo-request ===>
  	src=TN's link-local
  	dst=NUT's link-local


  State: INCOMPLETE (for TN)


  Wait (3 sec. * MAX_MULTICAST_SOLICIT)


  <=== Judgment #1: multicast NS ===
  	src=NUT's link-local
  	dst=solicited-node[TN's link-local]
  	w/ SLLA


  <=== Judgment #1: multicast NS ===
  	src=NUT's link-local
  	dst=solicited-node[TN's link-local]
  	w/ SLLA


  <=== Judgment #1: multicast NS ===
  	src=NUT's link-local
  	dst=solicited-node[TN's link-local]
  	w/ SLLA

JUDGMENT

  1. NUT sends the following multicast NSs:
     src=NUT's link-local, dst=colicited-node[TN's link-local], w/ SLLA
     
     1.1. A Number of the multicast NSs <= MAX_MULTICAST_SOLICIT(3)

     1.2. Intervals between the multicast NSs >= 3.0 sec.

TERMINATION

A CASE OF A HOST

Set NUT's retrans time to the default (1 sec) with RA with RetransTimer=1sec.
Send RA with RouterLifetime=0 to flush the Default Router List.

  ==== unsolicited RA ===>

        dst=all-node
        M=0, O=0
        Lifetime=0, ReachableTime=0, RetransTimer=0

A CASE OF A ROUTER

  The test does not invoke any remote command.
