I think that the solution I have proposed will work for IPv4 but not for
IPv6. Anyway If you could tell us if it works for IPv4 it will be great.
Thanks

Hi Martin,
Could you try to replace IFA_ADDRESS by IFA_LOCAL in the file
lispd_iface_mgmt.c (I think that is just two lines) ? We couldn't
test it but according to netlink documentation it should work. Let us
know the result in order to add the fix to github.
Regards
Albert

Hello,
It seems to work with ny quick and dirty fix by adding this code to
"is_link_local_address" to lisps_lib.c
inet_pton(AF_INET,"10.64.64.64",&(ipv4_network));
inet_pton(AF_INET,"255.255.255.255",&(mask));
if ((addr.address.ip.s_addr & mask) == ipv4_network){
is_link_local = TRUE;
}
Maybe you can option in config file to ignore RFC1918 IPs?

Hi Martin,
We have never found this problem. We will try to reproduce it and fix
it. Thanks for your fed back.

Hi,
I’ve a problem with LISPmob on OpenWRT, that occurs when the 3G
Stick is reconnecting. After reconnect LISPmob uses 10.64.64.64
(actually the default Gateway of this connection) as new RLOC and
also pushes that information to the Map Servers of the beta
network. I used the default web interface of OpenWRT 12.09 to
configuring the 3G connection. A restart of LISPmob is the only
way to fix it. Here are some informations and a log snippet:
ifconfig (before reconnect):
3g-drei Link encap:Point-to-Point Protocol

ifconfig (after reconnect):

What can I do that LISPmob doesn’t use the wrong IP as RLOC?
