Hi,<br>&nbsp;&nbsp;&nbsp;I am doing IPv6 Interoperability test, by using FreeBSD 7, where in there is a test case failed(&#39;<a href="http://host.router.1_7_A.sc">host.router.1_7_A.sc</a>&#39;), i think this is because&nbsp;of&nbsp;the&nbsp;FreeBSD&nbsp;router&nbsp;by&nbsp;default&nbsp;will&nbsp;not&nbsp;enable&nbsp;&#39;Router&nbsp;Header&nbsp;processing&#39;. When REF1 send ICMP6 Echo request FreeBSD machine(Tar) replys back with ICMP6 &#39;Parmeter problem&#39;. One good think is that the same test case passed when Linux machine act as a router.<br>
<br>Just i was looking abut this problem in internet, the FreeBSD 7 release note says <br>&quot;Processing of IPv6 type 0 Routing Headers is now controlled by the<br>   net.inet6.ip6.rthdr0_allowed sysctl variable, which defaults to 0<br>
   (off). For more information, see security advisory<br>   FreeBSD-SA-07:03.ipv6. [MERGED]&quot;<br><br>I tried the same option in Router and it was not working for me...<br><br>tar2# uname -a<br>FreeBSD <a href="http://tar2.ipv6logo.hp.com">tar2.ipv6logo.hp.com</a> 7.0-RELEASE FreeBSD 7.0-RELEASE #0: Sun Feb 24 19:59:52 UTC 2008     root@logan.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386<br>
<br>tar2# sysctl -w net.inet6.ip6.rthdr0_allowed=1<br>sysctl: unknown oid &#39;net.inet6.ip6.rthdr0_allowed&#39;<br><br><br>Please help me any of know about this problem.<br><br><br>Thanks in Advance,<br>Regards,<br>Arul<br>
