For the routing and so on, make sure the network is working without MIPL first i.e. you are able to ping between the nodes, etc., when MIP is not running.
Is your AR a dedicated box or a router? Also, why does your MN have multiple IPs. Is this part of your experiment or just some anomaly? On 4/2/07, Kris Bellemans <[EMAIL PROTECTED]> wrote:
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...
