Hi,

Has anyone used NetBSD machine for IPv6 Phase 2 Interoperability Testing?

We are using NetBSD 4.0.1 as the other Target node for testing our product.

The following 2 test cases under PMTU category are failing.

*Failures:*

IP6Interop 1.6a
IP6Interop 1.6b

*Test Setup:*

          TH1 / TR2
                |
-------------------------- (Network1) MTU 1500
  |
TR1
  |
--------------------------- (Network2) MTU 1280
                  |
            Ref-Host1

*Observations:*

* The max PMTU size in NetBSD is 1280.

*  When we transmit echo requests from Ref-Host1 to TH1/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 default fragmented irrespective of
the MTU size configured on the interface.

* Because of this behaviour of NetBSD stack, We are unable to complete the
interop testing of our product.

Kindly help us in resolving this issue.
