=head1 NAME

routerSendUnsolRaMax - NUT sends configured RAs.

=head1 TARGET

  Router only

=head1 SYNOPSIS

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

=head1 INITIALIZATION

  Start NUT advertising RAs:

    MaxRtrAdvInterval                   10
    MinRtrAdvInterval                   7
    AdvCurHopLimit                      64
    AdvManagedFlag&AdvOtherConfigFlag   False
    AdvDefaultLifetime                  9000 (max value)
    AdvReachableTime                    3600000 (max value)
    AdvRetransTimer                     0
    AdvOnlinkFlag&AdvAutonomousFlag     True
    AdvValidLifetime                    2592000

    AdvLinkMTU                          1500

=head1 TEST PROCEDURE

=begin html
<B>routerSendUnsolRaMax</B> verifies that NUT sends RAs
<UL>
<LI>whose parameters are as same as <A HREF="#INITIALIZATION">configured</A>.
<LI>that may contain a Prefix option and/or a MUT option and/or SLL option.
</UL>

=head1 NOTE

  TBD

=head1 REFERENCE

=begin html
<pre>
RFC2461
<hr>
6.2.4.  Sending Unsolicited Router Advertisements<br>
   A host MUST NOT send Router Advertisement messages at any time.<br>
   Unsolicited Router Advertisements are not strictly periodic: the
   interval between subsequent transmissions is randomized to reduce the
   probability of synchronization with the advertisements from other
   routers on the same link [SYNC].  Each advertising interface has its
   own timer.  <b>Whenever a multicast advertisement is sent from an
   interface, the timer is reset to a uniformly-distributed random value
   between the interface's configured MinRtrAdvInterval and
   MaxRtrAdvInterval; expiration of the timer causes the next
   advertisement to be sent and a new random value to be chosen.</b>
