Hello,<br><br>This is Arul, presently i am working on IPv6 Phase-2 interoperability test by using vel-1.0.4.<br>There is a test scenario, which is hanging in our testing when FreeBSD7 or Redhat Enterprise Linux 5 act as a router.<br>
<br>The test case name is "<a href="http://host.router.1_7_A.sc"; target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">host.router.1_7_A.sc</a>",it is hanging inside "command setup_cleanup_TAR2" at "sync finish_router_setup" after successfully executed "execute rtadvd -c /tmp/rtadvd.conf dc0".<br>
This is common for both FreeBSD and Redhat Enterprise Linux. Apart from this issue all other scenarios ran successfully.<br><br>Log:<br>-----<br><i>setup_cleanup_TAR2@TAR2 : 0.007146 : execute-EXECUTE<br>setup_cleanup_TAR2@mgr : 0.206992 : execute TAR2 ("/bin/sh -c echo > /dev/null")<br>
