Hi Musab,
First of all, thank you very much for your feed back. It is very
important for us to improve LISPmob.
If I understood correctly, you have found this segmentation fault when
using IPv6 EIDs over IPv4 RLOCs? Could you send the logs at level 2 when
this bug is produced? I have tried to reproduce it without success. The
configuration file is the same you sent me in a previous mail? The
segmentation fault is produced when you ping a specific destination or
is in general?
Thanks again for your support
Regards
Albert

Hi all,
I have sent a message above about the problem I am having using LISP
on IPv6. I was having a segfault issue whenever I start the lisp
daemon and attempt to ping or browse a site. This happen when the IPv6
network is tunnelled through IPv4 network. After troubleshooting the
problem with Lori and florinc on freenode chat, we realised that the
'map_cache_entry->mapping' is a NULL pointer and was causing the
segmentation fault. Please see the crash report here gdb lisp-crash
report - Pastebin.com <http://pastebin.com/q5W85Yps> and here to see
the null pointer (gdb) print map_cache_entry $1 =
(lispd_map_cache_entry *) 0x8370258 (gdb) pri - Pastebin.com
