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 and here to see the null pointer (gdb) print map_cache_entry $1 = (lispd_map_cache_entry *) 0x8370258 (gdb) pri - Pastebin.com
