[support] Re: [Dsmip] Re: IPv4-IPv6 handovers issues

[Etienne Allovon]

Hi,

I think that Kien means that the scenarii you describe (at least *IPv4 FL
--ho--> IPv6 FL*) should work with the base version of DSMIPv6
(umip-dsmip-2008053 with the 13 patches).
You should see if this scenario work with the base version of DSMIPv6 before
trying to debug it with the bug-fixes-patches and the ipv4-traffic-patches.

Kien, I took the liberty to precise your message because I didn't get its
sense at the first reading. Thus, if it can help others :-)
I apologize if Kien's sentence was obvious for everybody !

Regards,
Etienne
