<DIV><SPAN class=839035115-15052007><FONT face=Arial size=2>I =
didn't see a test
in the test suite to test a certain paragraph in section 3.1 of RFC =
2461.
<BR>The certain paragraph is as follows:</FONT></SPAN></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><SPAN class=839035115-15052007><FONT face=Arial
size=2> Multiple prefixes can be =
associated with
the same link. By<BR> default, hosts =
learn
all on-link prefixes from Router<BR>
Advertisements. However, routers may be configured to omit
some<BR> or all prefixes from Router
Advertisements. In such cases =
hosts<BR>
assume that destinations are off-link and send traffic to
routers.<BR> A router can then issue =
redirects as
appropriate.</FONT></SPAN></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><SPAN class=839035115-15052007><FONT face=Arial size=2>Note =
the last
sentence of the para above that says if an IPv6 host has received an RA =
from the
IPv6 router <BR>where RA does not advertise any prefix, then the host =
has to
send all its traffic to the IPv6 router. <BR>Without a prefix =
advertised, a host
has no information on prefix length nor any way to find out if any
<BR>destination is off-link or on-link when the host has to send a =
packet out.
That is why RFC 2461 says host <BR>has to send all its traffic to the =
router for
the case when router hasn't advertised any
prefix. </FONT></SPAN></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><SPAN class=839035115-15052007><FONT face=Arial =
size=2>Therefore when an
IPv6 host has to send out a packet and if the host issues an NS to try =
and
resolve<BR>the packet destination, then the host is not compliant to =
this para
in of RFC 2461. The host should <BR>just send the packet out since this =
host has
received an RA with no prefix advertised.</FONT></SPAN></DIV>
