Hi,<br><br>Has anyone used NetBSD machine for IPv6 Phase 2 Interoperability=

 Testing?<br><br>We are using NetBSD 4.0.1 as the other Target node for tes=

ting our product. <br><br>The following 2 test cases under PMTU category ar=

e failing.<br>

<br><b>Failures:</b><br><br>IP6Interop 1.6a<br>IP6Interop 1.6b<br><br><b>Te=

st Setup:</b><br><br>          TH1 / TR2  <br>   =

             |<br>-------------------------- (Netwo=

rk1) MTU 1500<br>  |<br>TR1<br>  |<br>--------------------------- (Netw=

ork2) MTU 1280<br>

                  |<br>            =

Ref-Host1  <br><br><b>Observations:</b><br><br>* The max PMTU size in Net=

BSD is 1280.<br><br>*  When we transmit echo requests from Ref-Host1 to T=

H1/TR2 with data size 1500, No "Packet Too Big" Messages are sent=

 by our Router (TR1) since the packets (size greater than 1280) are by defa=

ult fragmented irrespective of the MTU size configured on the interface.<br=

<br>* Because of this behaviour of NetBSD stack, We are unable to complete =

the interop testing of our product.<br><br>Kindly help us in resolving this=

 issue.<br clear="all"><br>-- <br>Regards,<br>Srinidhi<br>
