NAME

sendUcastNS - Verify that NUT sends unicast NSs by the default config.

TARGET

Host and Router

SYNOPSIS

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

INITIALIZATION

  Clear NC state for TN.

TEST PROCEDURE

sendUcastNS verifies NUT send unicast NSs by the default rules:

  - MAX_MULTICAST_SOLICIT
  - RETRANS_TIMER

  TN		  NUT

  State: NONCE (for TN)


  ==== echo-request ===>

JUDGMENT


  1. NUT must send at the least one multicast NS:
     src=NUT's link-local, dst=sol-node[TN's link-local], s/ SLLA

  2. NUT must send an echo-reply:
     src=NUT's link-local, dst=TN's link-local

  3. NUT must send an echo-reply:
     src=NUT's link-local, dst=TN's link-local

  4. NUT must send unicast NS:
     src=NUT's link-local, dst=TN's link-local, w/ or w/o SLLA


     4.1. The number of the unicast NSs <= MAX_UNICAST_SOLICIT(3)


     4.2. Intervals between the unicast NSs >= RETRANS_TIMER(1 sec.)

TERMINATION

N/A

NOTE

  The test does not invoke any remote command.
