Hi,
I'm a student and I'm doing a project on MobileIPv6.
I've followed the howto at
http://gnist.org/~lars/doc/Mobile-IPv6-HOWTO/Mobile-IPv6-HOWTO.html
to configure my MIPL-setup but I'm still experiencing some difficulties.
When I move the MN to the visit_net, I can't ping the AR on address
fec0:106:1100::1. I can ping the AR's
link-local address fe80::230:4fff:fe48:a9ec though.
Although the MN's default gateway has changed to the AR's link-local address, I
can't access the rest of the network.
I've been looking in the mailing list for an answer but I couldn't find a
solution for my problem...
