<P>
Hi to all,<BR>
I am a new member to this list.<BR>
I am working o=
n IPv6 Implementation for Montavista Linux ( MVL-3.1, RTOS by Samsung).&nbs=
p; <BR>
<BR>
I am sending you all my problem. pls check it.<BR>
<BR>=
While Conformance testing for IPv6-Over-IPv4 Tunnel , I am facing proble=
m. I am using BSD as Tester node and MVL as NUT and configured as router.<B=
R>
<BR>
While testing for 12th test case ( Fragment.seq ) Tester Node s=
ends a packet of 1280 and expecting a reply from Node under Test wtih a pac=
ket length of 1300 with DF either SET or NOT SET. From the packet data it i=
s clear that NUT is sending a packet with 1300 length and DF bit is SET. Bu=
t, the script says that it has got a packet wtih a packet length of 1300 wi=
th DF bit NOT SET and depending upon that it sets:<BR>
<BR>
IPv4-PMTU =
= OFF;<BR>
<BR>
but It should set it as: IPv4-PMTU = ON;<BR>
<BR>=
Next it send a packet with 1400 after setting sit MTU = 1400,&nbsp; it=
 gets a reply with a packet length 1420 with DF SET which is correct accord=
ing to RFC-2893&nbsp; (Page no -11, Topic 3.2 : Tunnel MTU and Fragmentatio=
n&nbsp; ).But, script says that it's not the correct reply and says that te=
st failed.<BR>
<BR>
I feel is that there is some problem with the scrip=
t. Please let me know where is the actual problem . If any Modified script =
is available please let me Know.<BR>
<BR>
Thanks and Regards,<BR>

Here is the packet details:<BR>
<BR>

3. recv v6over=

(this is what script says it=
 has received from NUT as reply but it is clear from packet data that is ha=
s got :<BR>
(recv v6overv4_echo_request_LINK1_nut2tn_1300_DF). Packet dat=
a is at the end of Mail.)<BR>
<BR>
<BR>
<BR>
4.(This is what script=
 decides but it should decide as NUt uses IPv4 path MTU and should set IPv4=
-PMTU = ON; but it sets IPv4-PMTU = OFF;) <BR>
NUT use the MTU of the=
 link layer (under IPv4)&nbsp; <BR>
<BR>
5. (This is what script sends =
next)<BR>

TN can receive Echo Reply from NUT<BR>
