Subject: [users:00378] About IPv6 type 0 routing headers issue

Tahi users and developers,

   As well-known,when the type of IPv6 routing header is set to IPV6_RTHDR_YPE_0, 

it would allow remote attackers to cause a denial of service via

crafted IPv6 type 0 route headers that create network

amplification between two routers.

   In the current time,the solution which is adopted by many products 

wil cause IPv6 type 0 routing headers to be ignored. But the test scripts

from www.tahi.org dont ignored IPv6 type 0 headers. 

   So when we are having a IPv6ready Certification,some tests about 

IPv6 type 0 routing header will fail if Self_Test from www.tahi.org 

isn't modified.


   how should we process this case when we are ready to have a IPv6ready 

Certification?

   please refer to
