If it's possible to start a MN in a foreign network I have a problem the.
Because as I said, no Binding Update are send trough the MN's interface (I
sniff the traffic with ethereal). Therefore, HA can't update is binding
binfing cache..
On the contrary when I start the romaing in the home network alll is ok.

HI
You can start MN in a foreign network ... there's no limitation on mip6d
about it.

Hi everyone
I was wondering if it was mandatory to start the Mobile Node in the home
network.
I tried to initialize mip6d in the foreign network and these are the debug

What I understand from this log is that : the MN knows it is in a foreign
network and then tries to send Binding Update to the HA. If I'm right, I
didn't sniff any Bindig Update with Ethereal and the binding cache of the
HA is empty.
In RFC3775, it doesn't tell anything about the starting of a MN in a
foreign network, am I wrong??
Could anyone tell the way mip6d is implemented in this case??
Thank you
Best Regards
Mathieu
