TEST PROCEDURE

hostSendRsAfterUnsolicitedRa verifies that NUT does not send a RS After receiving a solicited RA.

After receiving a valid RA



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


  <=== Judgment #1: RS ====
       src=unspecified or NUT's link-local
       dst=all-router
       w/o or w/ SLLA


  ==== Valid RA ===>
       src=link-local
       dst=all-node
       w/ or w/o SLLA
       timeout=600 sec.


  Judgment #2: NUT does NOT captures any packet from NUT within 4 sec.

After receiving an invalid RA



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


  <=== Judgment #1: RS ====
       src=unspecified or NUT's link-local
       dst=all-router
       w/o or w/ SLLA
       timeout=600 sec.


  ==== Invalid RA ===>


  Judgment #2: NUT captures at the least one RS from NUT within 4 sec.

JUDGMENT

1. NUT sends a valid RS:


     A) src=unspecified, dst=all-router, w/o SLLA
     B) src=NUT's link-local, dst=all-router, w/o SLLA
     C) src=NUT's link-local, dst=all-router, w/ SLLA


2. Sending RSs

6.3.7.  Sending Router Solicitations


   Once the host sends a Router Solicitation, and receives a valid
   Router Advertisement with a non-zero Router Lifetime, the host MUST
   desist from sending additional solicitations on that interface, until
   the next time one of the above events occurs.  Moreover, a host
   SHOULD send at least one solicitation in the case where an
   advertisement is received prior to having sent a solicitation.
   Unsolicited Router Advertisements may be incomplete (see Section
   6.2.3); solicited advertisements are expected to contain complete
   information.

TERMINATION

  Send RA with RouterLifetime=0 to clear the Default Router List.
