I find a way to solve my problem. In fact, I didn't have any site-local address so multicast messages, which are sent to ff05::15, didn't find any "site-local PC". So I just change in the olsrd.conf file the multicast IPv6 line;
So
	IP6MULTI	auto
became
	IP6MULTI	ff0e::1

And now it works well. I don't know if this change can create other problem later but I don't think so.

Hmmm... I seem to remember having delt with this problem before.

I am CCing this to the olsr-users list. Perhaps somebody else has experienced the same problem?

Please direct olsrd related questions to the mailinglist ;)
