NAME

hostRecvRas2 - Verifying that a host accept the union of all RAs

TARGET

Host only

SYNOPSIS

 hostRecvRas2.seq [-tooloption ...] -p hostRecvRas2.def

INITIALIZATION

1. Clear the Prefix List that was learned with RAs.
2. Create a neighbor cache entry for TN, Y, Z where the IsRouter flag is TRUE.
3. Set their state to REACHABLEs.
4. Give three global prefixes by TN, Y and Z:
   • 3ffe:501:ffff:100::/64
   • 3ffe:501:ffff:108::/64
   • 3ffe:501:ffff:107::/64

TEST PROCEDURE

hostRecvRas verifies that a host accept the union of all RAs.

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


  State: REACHABLE (for all)


  ==== echo-request ===>
       src=off-link global, but LLA is TN's one
       dst=NUT's global, prefix==3ffe:501:ffff:100::/64


  <=== Judgment #2: echo-reply ====
       src=NUT's global, prefix==3ffe:501:ffff:100::/64
       dst=off-link global, but LLA is one of the routers(TN, Y, Z)


  ==== echo-request ===>
       src=off-link global, but LLA is TN's one
       dst=NUT's global, prefix==3ffe:501:ffff:108::/64


  <=== Judgment #2: echo-reply ====
       src=NUT's global, prefix==3ffe:501:ffff:108::/64
       dst=off-link global, but LLA is one of the routers(TN, Y, Z)


  ==== echo-request ===>
       src=off-link global, but LLA is TN's one
       dst=NUT's global, prefix==3ffe:501:ffff:107::/64


  <=== Judgment #2: echo-reply ====
       src=NUT's global, prefix==3ffe:501:ffff:107::/64
       dst=off-link global, but LLA is one of the routers(TN, Y, Z)

JUDGMENT

  1. NUT accepts the union of all received information; the receipt of
     a RA must not invalidate all information received in a previous RA
     or from another source.

  2. NUT throw three echo-replies to the default router (i.e. TN),
     and their source addresses are different global prefixes.

TERMINATION

  Send the follwoing RAs to clear the Default Router List:
  - RA (src=TN) with RouterLifetime=0
  - RA (src=Y)  with RouterLifetime=0
  - RA (src=Z)  with RouterLifetime=0

  Clear the Prefix List by remote command. XXX

NOTE

  The test invokes the following command:
  - Clear the Prefix List
