(usagi-users 03814) Re: Tunneling problems

Hello,

Your patch breaks MIPL2 about RFC specification.
We need the route entry by HA to support sending ICMP error/MH packet below:
 o destination address is a home-registered HoA
 o source address is HA
 o to home link

For the detail, see TAHI Project conformance test to understand it easier.
The items are e.g. HA_1_1_[567] and HA_3_3_X on the below web site:
http://cert.v6pc.jp/mipv6/doc-3.3/mipv6-ha-4.0.4/index.html


Thanks,
